In June, 1965, the Detroit Edison Company filed a petition pursuant to CL 1948, § 486.251 et seq. as amended (Stat Ann 1968 Cum Supp § 22.1671 et seq.) for condemnation in the probate court for Oakland county, seeking to acquire a fee interest in a 200-foot wide strip of land across defendants’ property. The use avowedly planned for this strip was the construction of a major high-power transmission line to assist the power company in meeting increasing demands for electrical power in southeastern Michigan. Since 1956 there had existed between the parties a written instrument which conveyed an easement right to Detroit Edison in the identical strip for purposes of constructing a tower transmission line thereon. Expert witnesses testified that the existence of the easement and towers presently constructed thereon affected their valuations.

This case was heard by a condemnation commission under the rules of the probate court. The commission was instructed in the law by the probate *616judge and returned a report setting damages to the defendants of $11,390 and this award was confirmed by the probate court. By virtue of GCR 1963, 806.1, final judgments in probate courts are appealable directly to this Court if they are not triable de novo in the circuit court. Condemnation actions by water, electricity, and gas companies are not triable de novo in the circuit courts, and thus are appealable directly to the Court of Appeals. In re petition of Detroit Edison Company (1961), 365 Mich 35; Michigan Gas Storage Co. v. Gregory (1954), 341 Mich 34. Such a procedure has been followed in this case.

Defendants raise these five general claims of error on appeal: that they were improperly denied a pretrial conference; that the parol evidence rule was improperly applied to exclude oral negotiations surrounding the 1956 easement grant; that the probate judge improperly refused certain requested charges to the condemnation commission; that the question of necessity for taking a fee interest was not proved; and that the probate court improperly affirmed the award while there vías a contemporaneous trial in the circuit court which claimed fraud in the 1956 easement grant.

When the present court rule 301 was first promulgated, pre-trial conferences were not required in condemnation eases. See Committee Notes, 2 Honigman & Hawkins, Michigan Court Rules Annotated (2d ed), p 5. Since that first promulgation, the. theory of a condemnation case has changed from' being inquisitorial in nature to being a contested-judicial action by the adoption of the 1963 Michigan Constitution, specifically art. 10, § 2. The theory of this change is set out in State Highway Commissioner v. Lindow (1966), 4 Mich App 496. Defendants make the argument that they were improperly *617denied a pre-trial conference under the Lindow precedent and under the wording of GrCR 1963, 301.1:-

“In every contested civil action the court shall direct the attorneys for the parties to appear before it for a conference.”

The general court rules do not generally govern the practice in probate court. GrCR 1963, 11.1. Separate rules are established in Michigan for probate practice. Honigman & Hawkins, Manual of Michigan Rules (1963), 331-339. The power and supply companies condemnation statute is silent in regard to pre-trial conferences. It is the opinion of this Court that it was not error in this case for the probate court to have denied the motion for a formal pre-trial conference. Our conclusion is reinforced by the fact that an informal pre-trial conference was held and the defendants have made no showing of prejudice by the denial of a formal conference.

It is the general and Michigan rule that where a contract is clear and unambiguous, parol evidence of negotiations cannot be admitted to vary the contract. Salzman v. Maldaver (1946), 315 Mich 403; D. N. Osborne and Co. v. Wigent (1901), 127 Mich 624; 32A CJS, Evidence, § 851, p 211; 30 Am Jur 2d, Evidence, § 1029, p 164. The easement contract clearly called for the erection of a high-power tower transmission line. Defendants argue that they sought to introduce evidence that would show that the easement granted was only for smaller towers than the power company now plans to construct, and which would carry less power than is now proposed. They argue that the proffered evidence would show implied conditions and that the power company was seeking to increase improperly the *618burden of the easement, in violation of the precedent of Delaney v. Pond (1957), 350 Mich 685.

The easement grant clearly allowed the construction of a high-power line. Technical aspects of the transmission line were not denoted in the contracts, nor would we have expected as much. Science and technology do not stand still. Reasonable men would expect some change in tower design, capacity, or material composition in the span of a decade. The law does not require the cessation of scientific advancement and in this case, will not permit the parties to claim they contracted to such a cessation a decade ago, when the written contract itself is clear and does not require such a finding. Defendants’ parol evidence was properly excluded.

One of the two rejected charges proposed by the appellants was worded in such a manner that it would have included much of the same information concerning the negotiations surrounding the 1956 easement grant which was excluded under the parol evidence rule. We have ruled that the exclusion of the evidence of negotiations was not erroneous. It also was not erroneous to refuse to give the requested charge which would have negated the parol evidence ruling for practical purposes.

The other requested charge was that if the commission found a part of the testimony of an expert witness was incorrect or based on a false premise, then the entire testimony must be disregarded. Such a charge would have been erroneous. If the testimony was false in one respect, the commission could have, in its discretion, disregarded all of the testimony, or it could have given credence to that testimony supported by other evidence. People v. Hunter (1963), 370 Mich 262; Western Michigan University v. Slavin (1967), 6 Mich App 291.

On the question of necessity, the defendants argue that there was no proof of the necessity of taking a *619fee interest in the land. This argument is based on an excerpt of testimony of a witness for the power company which indicated that one of the reasons for seeking a fee interest in the strip arose out of a sense of fairness to the property owners. Complaints had been received from owners of other property encumbered by easements for similar construction, that the landowners should not have to pay taxes on the land under the power lines, of which they had only a very restricted use. The defendants argue that a sense of fairness towards the landowners is not a showing of necessity and that the individual landowners are the best judges of fairness in any given case. Defendants, in proposing this argument, seem completely to ignore additional testimony which tended to show a need for a fee interest in the strip of land which lies under and to either side of the power lines. Evidence was introduced of factors associated with the line construction and maintenance which would be inconsistent Avith anything except a fee ownership. The power company insists upon a prohibition against structures under the line or near the towers, primarily because of the danger of a fire damaging the line so as to cause a major power failure. The power company also cuts down all trees which would in any way interfere with the power line. It is the opinion of this Court that the condemnation commission had sufficient evidence upon which to base its findings of the necessity for the taking of a fee interest.

Finally, defendants claim that the probate court erred in affirming the award Avhile there was a contemporaneous action pending in the circuit court, claiming fraud in the 1956 easement grant. It would have been preferable to have all possible litigation disposed of before the confirmation in this case, hoAArever, courts must move Avith dispatch on *620the cases before them. Theoretical or possible influence on a given case by pending or potential collateral cases should not oversway court rulings. At the time of confirmation of the award, this case was complete and the court explicitly followed the confirmation statute. CL 1948, § 486.252(e) [Stat Arm 1968 Cum Supp § 22.1672(5)]. "We find no reversible error in the confirmation of the award.

The judgment of the probate court is affirmed. Costs to appellees.

{dissenting). In 1956 the Zoners signed Detroit Edison’s printed form tower line permit and received $2,000. The permit or easement granted Edison

“the right to construct, operate and maintain its lines for transmission and distribution of electricity and company communication facilities, including the necessary towers, fixtures, wires and equipment”

over a 200 foot wide corridor running through the Zoner property and requires payment to the Zoners of an additional $400 for each tower erected.

Nine years later, in 1965, Detroit Edison commenced these proceedings to condemn the fee simple interest in the 200 foot corridor covered by the easement. The condemned lands were sought by Detroit Edison for the construction of a 345,000 volt power line, a line considerably larger than any theretofore constructed in Michigan. The line is to be supported on towers roughly 50% higher than the average or normal tower theretofore built in the State with corresponding enlargement of the base of the tower. Two 141 foot towers and one 126 foot tower will be constructed on the Zoner portion of the corridor. *621The easement obtained in 1956 was acquired for the construction of the 345 KY line, which was then in the planning stage; there is no evidence as to whether this was disclosed to the Zoners.

At the hearing the Zoners sought to establish through Mr. Zoner’s testimony that Detroit Edison’s right-of-way man had advised Mr. Zoner before the Zoners signed the tower line permit that the height of the towers would not exceed the height of towers theretofore constructed in Michigan and specifically that the height of the towers that would be constructed on the Zoner land would not exceed 85 to 90 feet. The trial judge refused to permit that testimony to be heard by the commissioners and a separate record was made after the judge had ruled the testimony inadmissible. The testimony was excluded under the parol evidence rule.

Detroit Edison’s expert witness predicated his evaluation of the Zoner property sought to be condemned in fee simple on the assumption that Detroit Edison already had the right under the 1956 easement to build thereon the 345 KV line. At trial and now on this appeal Detroit Edison successfully contends that the words in the easement grant mean lines and towers of any size and height without limitation. The Zoners asserted then and now again unsuccessfully assert that the words mean lines and towers no larger than those theretofore known in this State, both as a matter of construction of the language used in the easement and because that is the meaning which both parties, the Zoners and Detroit Edison through its right-of-way man, agreed upon before the easement was signed.1

*622The function of the parol evidence rule, a rule of substantive law, not of evidence,2 is to protect the stability of transactions evidenced by writings by excluding relevant evidence of probative value lest the content of the writing be emasculated at tho hands of a jury.3

The rule does not, however, prevent the judge,4 who traditionally interprets a writing, from con*623sidering extrinsic evidence on the 3 critical issues which are

(1) Did the parties enter into an oral understanding before the writing was executed that was not embodied in the writing?

(2) Did the parties intend the writing to replace the alleged antecedent oral understanding?

(3) The meaning of the words used in the writing intended by the parties.

In this case, both the trial judge, and now a majority of this Court, rule that the words used in the easement grant are so plain and clear that one can decide by looking at them, without the benefit of a testimonial record, that there was no oral agreement regarding the height and size of the towers and, if there was any such oral agreement, both parties intended that such oral agreement be merged into and superseded by the writing, and what the parties intended by the words used in the writing.

In reaching that result, there being no extrinsic evidence of record, the trial judge and the majorit3r of this Court must have applied an objective standard, i.e., no reasonable man would have entered into such an oral agreement and failed to insist on its inclusion in the writing and no reasonable man could have understood the words used in the writing to mean towers no larger than those theretofore built in Michigan (see footnote 7 and accompaiiying text).

In passing upon such matters judges should, I most respectfully submit, be especially cautious. It is one thing for a judge to hypothesize a reasonable man for judging an experience he may share on the *624same plane with, laymen. It is quite another to attempt the same feat in an area where the judge is not a layman hut an expert. Few laymen are as likely to look upon the oral statements of a representative of a respected utility company with the jaundiced eye of one experienced in law. Laymen, not lawyers, negotiated and signed the writing before us. As laymen, the Zoners are much more likely than a lawyer, who is subconsciously devoted to the parol evidence rule and aware of its possible impact, to enter into an oral understanding intended to survive execution of a contemplated writing. In such matters we need the light a testimonial record can provide, which alone will enable us to peer through the looking glass, and look beyond our own linguistic and professional experience to the world beyond where dwell those whose controversies we judge and whose life experience and approach to legal documents is likely to be different than ours.

With such a testimonial record before him, a judge can decide, giving due and solemn weight to the printed word, whether the alleged antecedent oral agreement was in fact entered into and, if so, whether it was in fact intended to survive the execution of the writing and the meaning of the words used in the writing intended by the parties when it was signed.

The foregoing is consistent with the cardinal rule for construing writings, to which all other rules are subordinate, namely, that a writing shall be interpreted so as to ascertain and make effective the intention of the parties.5 6 Our Supreme Court and *625other courts have said and done just that in eases like the one at bar.

On the use of parol evidence to show whether the writing before the court was intended to represent all the agreements of the parties, Professor Corbin observed:

“The writing cannot prove its own completeness and accuracy. Even though it contains an express statement to that effect, the assent of the parties thereto must still be proved. Proof of its completeness and accuracy, discharging all antecedent agreements, must be made in large part by the oral testimony of parties and other witnesses. The very testimony that the ‘parol evidence rule’ is supposed to exclude is frequently, if not always, necessary before the court can determine that the parties have agreed upon the writing as a complete and accurate statement of terms. * * *

“There is ample judicial authority showing that, in determining the issue of completeness of the integration in writing, evidence extrinsic to the writing itself is admissible. * * *

“It would have been far better had no such rule ever been stated. Instead, attention should be called to the accepted rule that parties can by a substituted contract discharge and annul any and all of their previously made contracts. Then the question should be put: Have the parties in the instant cáse made such a substituted contract? On this issue of fact, no relevant testimony should be excluded; it should all be observed and weighed with the clear and critical eye of experience. This is what the wiser courts, seeking justice in each case, have in truth been doing.” Corbin on Contracts, § 582, pp 448-451, 455.

On the use of parol evidence to show the meaning given by the parties to the words they used in a writing, the following from the Restatement of Contracts is instructive:

*626Ҥ 242. Effect of Prior Negotiations.

“Previous negotiations between parties to an integrated agreement, whether the negotiations relate to that agreement or to another, are admissible to show that the agreement has any meaning which is not impossible under the standard stated in § 230, though that meaning would not otherwise have been given to the agreement.

“Comment:

“a. Where the parties by the language they have employed leave their meaning obscure and uncertain when applied to the subject-matter, then the expressions and general tenor of speech used in the previous negotiations, even if coming as they usually must from one or the other of the parties themselves, are admissible to show the conditions existing at the time when the writing was made.6 And even where the writing is not ambiguous on its face, the circumstances under which the parties contract may be looked at to establish an ambiguity, as well as to indicate the proper choice of possible meanings; and the common knowledge and the understanding of the parties themselves as shown by their previous negotiations is sometimes such a circumstance. 1 There is, however, a limit to the application of the rule stated in the Section. Previous negotiations cannot give to an integrated agreement a meaning' completely alien to anything its words can possibly express.” (Emphasis supplied.)7

One of Professor Corbin’s greatest contributions was his work on the interpretation of writings and the bearing thereon of the parol evidence rule. Ho attempted to summarize as tentative rules of substantive law the principles which he had gleaned from his work; these include the following:

*627“The primary and ultimate purpose of interpretation is to determine and make effective the Intention of the Contracting Parties.” (Emphasis by author.!

“No party to a contract should ever be bound by an interpretation that is determined exclusively by the ling'uistic education and experience of the judge.”

“When a court excludes all relevant evidence of the meaning given to the words of a contract by the parties thereto, it is giving weight exclusively to its own linguistic education and experience.”

“When a court enforces a contract in accordance with an interpretation that seems ‘plain and clear’ to the court and excludes relevant convincing evidence that the parties intended a different interpretation, it is ‘making a contract for the parties’, one that they did not make.”

“No word or group of words in any language has an ‘objective’ meaning separate from and independent of its actual use by some person to convey his thought to another person.”

“No writing, whatever its form and content, is sufficient to establish its existence and operation as an ‘integration’ assented to as such by the parties.”

“When a valid contract is made (oral or written), the parties thereby discharge and displace antecedent agreements and negotiations (oral or written) that are inconsistent with it.”

“Relevant evidence, oral or written, offered by one party to prove an interpretation actually given by the other party, or to prove that the other party knew or had reason to know an interpretation actually given by the first party, is not rendered inadmissible by the fact that the words interpreted are contained in an integrated writing.”8

*628Under the foregoing, parol evidence is admissible to show that there was an antecedent oral agreement not intended by the parties to be integrated into the writing and also to prove an interpretation actually given by both parties to words contained in an integrated writing not inconsistent with the writing itself.9

*629In Magee v. Brown (1957), 347 Mich 638, the term “retail hardware business” was used in a covenant not to compete. After consideration of extensive testimony concerning the pre-closing negotiations of the parties and other matters, it was held that the term was not intended by the parties to cover retail sales made in connection with factory mill supply and manufacturing operations, a separate business of the covenantor.

The Court in In re Traub Estate (1958), 354 Mich 263 found an agreement to make a will leaving certain shares of stock to “Robert Traub” ambiguous on the issue whether Robert’s daughter was entitled to the stock if he predeceased the contracting testator, declaring, p 280:

“in event of ambiguity in an instrument we make use of all possible aids in construction, the parol evidence rule to the contrary notwithstanding. 3 Corbin, Contracts, § 579, p 250 [pp 420, 421 in 1960 ed] states the principle with clarity:

“ ‘As long as the court is aware that there may be doubt and ambiguity and uncertainty in the meaning and application of agreed language, it will welcome testimony as to antecedent agreements, communications, and other factors that may help to decide the issue.’ ”

In McCarty v. Mercury Metalcraft Company (1964), 372 Mich 567, plaintiff salesman sued for *630commissions under a contract which obligated the defendant to pay plaintiff 5% of all orders he secured. The defendant-appellant claimed the words “all orders” was meant to include only prototype orders and not orders for production. After listening to parol testimony the trial judge indicated he found no ambiguity, presumably, said our Supreme Court, because he had found plaintiff’s testimony not so unequivocally in agreement with defendant’s in regard to the meaning of the term “all orders”. That factual finding of no ambiguity was held on appeal to have been one that could reasonably have been made from the testimony adduced. In so holding the Supreme Court observed that a latent ambiguity is one

“ ‘where the language employed is clear and intelligible and suggests but a single meaning, but some extrinsic fact or extraneous evidence creates a necessity for interpretation or a choice among 2 or more possible meanings [citation omitted].’ Since the detection of a latent ambiguity requires a consideration of factors outside the instrument itself, extrinsic evidence is obviously admissible to prove the existence of the ambiguity, as well as to resolve any ambiguity proven to exist.” (Id, p 575, emphasis supplied.)

There is a substantial number of cases on the question of whether parol evidence is admissible to show a maximum construction cost was orally agreed upon although the written contract with the architect or builder does not reflect the same, the great majority holding the evidence admissible.10 Similarly, parol evidence is admissible to show an oral limitation on the maximum height of a tower.

*631The trial judge should have listened to the testimony concerning the alleged oral agreement regarding tower height and size before he made up his mind that there was no such agreement and, if there was any such agreement, that it was merged into the writing, and what meaning the parties intended to give the words used in the writing. Had he done so, he might well have concluded that the position being pressed by the Zoners was not as “impossible” as his ruling and that of this Court would make it appear.

From what little does appear in the record, I think it entirely possible that the alleged agreement was entered into between the Zoners and Edison’s right-of-way man. The words used in the easement grant need clarification. What kind of electrical lines? What kind of towers? It would have been natural and normal to have asked those questions. If Mr. Zoner did in fact ask those questions of the right-of-way man before signing the easement agreement and the latter did reply that “lines” meant high tension lines and “towers” meant “high rise steel towers”, I think it entirely possible that Mr. Zoner then would have gone on to ask the right-of-way man the size or height of the towers. If he did and the right-of-way man replied, as Mr. Zoner testified, “normal towers,” towers like you have seen around, towers not exceeding 85 to 90 feet in height, as presently visible in Michigan, then that is what the words meant to the parties and no court should substitute its understanding of those words for the agreement the parties themselves made before the writing was signed.11

*632Detroit Edison, no doubt, desires to be protected against being called upon to produce former employees, who may be unavailable, to refute possibly perjurious testimony; it may well believe its valuable easement rights would be unsettled by any rule of law which would impose that obligation. Detroit Edison can, however, largely protect itself against such an eventuality by the simple expedient of drafting its instruments so that all who read can understand what they mean. If Detroit Edison desires to obtain the right to build a “high tension power line,” it might consider using those words instead of the words “electrical lines.” If it desires to obtain the right to build “towers of unlimited size and height,” it might consider saying that in so many words.

True the words used by Detroit Edison in its tower line permit comprehend an electrical transmission system of the dimensions Detroit Edison claims it has the right to build, but those words also lend themselves to the more limited interpretation for which the Zoners contend; an interpretation which may well have been in keeping with their linguistic experience and that of the right-of-way man.12 Of course, Detroit Edison can draw its agreements any way it wishes without any advice from the writer, but it seems to me that if it prefers terseness to clarity it can reasonably expect that a question may be asked by a land owner before signing concerning the meaning of the cryptic words which it chooses to use. And if such questions are 'put and answered in the manner the Zoners contend they were, Detroit Edison should not be heard, having drafted the document in the form stated, to say that, even if a judge is persuaded to listen and he *633decides such an antecedent oral agreement was made and intended to survive execution of the writing, even if he concludes both the landowner and the right-of-way man agreed that “towers” means “towers no larger than those which have heretofore been built in this state”, a court may, nevertheless, substitute its own “objective” interpretation for that of the parties.

After the opinions in this case were released to the parties, but before they were released for publication by the State Reporter, the Michigan Supreme Court decided Keller v. Paulos Land Company (1968), 381 Mich 355. In that case, a land contract provided that the land contract purchaser would enjoy a “non-exclusive easement for purposes of ingress and egress.” The land contract purchaser claimed he was entitled to use the easement strip for parking purposes. After reviewing the testimonial and other record evidence and the competing contentions of the parties, the Supreme Court declared the quoted language ambiguous and held that “the trial court properly permitted oral testimony to determine the true intent of the parties. See McIntosh v. Groomes (1924), 227 Mich 215,” (discussed in footnote 5, supra) and affirmed the trial judge’s denial of an injunction against the purchaser’s use of the easement strip for parking purposes.
