Plaintiff Frigid Food Products was, for the purposes of 1965 Wayne County and City of Detroit personal property taxes, the owner of certain personal property. The original $110,590 tax assessment of that property was sought to be increased by the Board of Assessors of the City of *404 Detroit upon petition filed with the State Tax Commission. Over the duly-filed protest of plaintiff, the commission granted the request of that petition and increased the assessed valuation to $235,960, including $128,380 of farm products in storage in the General Cold Storage Warehouse. Thereafter, the County of Wayne submitted a supplementary tax bill to plaintiff in the amount of $1,052.17 and the City of Detroit similarly submitted a supplementary tax bill in the amount of $5,327.52. Both amounts were paid to the appropriate treasurers, under protest, on February 18, 1966.

The order of the State Tax Commission increasing the assessment was based upon their conclusion that plaintiff’s farm products stored in General’s warehouse were not entitled to the exemption from personal property taxation contained in MCLA § 211.9 (Stat Ann 1970 Cum Supp § 7.9), based upon a finding that plaintiff and General were “affiliated” corporations within the meaning of that statute which provides in part:

“No portion of a public warehouse, dock or port facility leased to a tenant or no portion of any premises owned or leased or operated by a consignor or consignee or any affiliate or subsidiary of such consignor or consignee shall be deemed to be a public warehouse, dock or port facility.”

Plaintiff challenged the assessment in Wayne County Circuit Court. At the pre-trial conference plaintiff included challenges to the constitutionality of the statute as being too vague and failing to set forth intelligible standards for defining the term “affiliate”. Defendants objected to the inclusion of the constitutional issues and plaintiff subsequently withdrew the objection. The issue before the circuit court was whether General Cold Storage Warehouse was an affiliate of Frigid Food Products so as *405 to exclude plaintiff from the personal property tax exemption.

The trial court found that Frigid and General were affiliated and that the assessment was proper. This decision was based upon a determination that “affiliated” means “connected” and that plaintiff did not establish its right to an exemption by a preponderance of the evidence.

Plaintiff attempts to raise the constitutional issue again on appeal. This Court will not entertain a question which was not raised in the pleadings, was specifically withdrawn by plaintiff at the pretrial conference, and where it is apparent on the record that plaintiff not only could but did decide to proceed without reference to the principles of constitutional law. Mitchell v. Grewal (1953), 338 Mich 81, 87; Ridenour v. County of Bay (1962), 366 Mich 225, 243; Azzaro v. Stupar (1969), 17 Mich App 170, 172.

Divested, by its own actions, of constitutional questions, the appellant’s case before this Court is based upon affirmance or reversal of the trial court’s holding that appellant’s connection with General Cold Storage Warehouse comes within the definition or application of “affiliate” as used in the exemption clause of the act under review here.

Only in the case of the Board of Directors of General Cold Storage {re: Philip Wechsler) is there a lack of complete duplication of the parties on the opposite side of the above ledger. A mere fleeting glance at such ledger would ring bells of affiliation in the mind of even a trainee tax collector, much less the hawk-eyed tax agents of appellees.

The trial court below held there was a showing of some evidence of affiliation or relationship between Frigid and General and, therefore, the exemption was not available to Frigid. We agree.

Statutes and provisions exempting persons or property from taxation are strictly construed, McConnell v. Township of Lake (1916), 191 Mich 544; Remus v. City of Grand Rapids (1936), 274 Mich 577. To construe the exemption provision of the statute under examination to not include the fact situation now before this Court would be to hold “affiliate” a meaningless word. Such is the argument, in law, of appellant here. With such argument we cannot and do not agree.

*407 This Court finds in these cases of Frigid Food Products v. City of Detroit and Frigid Food Products v. County of Wayne that there was a definite affiliation between plaintiff and General Cold Storage as that term is generally understood in its common usage. MCLA § 8.3 (Stat Ann 1969 Rev § 2.212).

Affirmed. No costs, a public question being involved.
