Section 164 of the present Code provides, that the bonds of tax-collectors, and many other officers specified, “shall be invalid and insufficient in law, unless the sureties upon such bonds respectfully reside in the county in which the duties of such officers are to be performed.”

The only question presented by the present appeal is, whether the non-residence in a county of one of the several sureties so far vitiates the bond as to destroy its binding force upon the obligors setting up such defense. One of the sureties on the tax-collector’s bond, here sued on, is shown to reside out of the -county of Clarke — the county in which the duties of this officer were to be performed' — his place of residence being in' an adjoining county; and this fact is averred by special plea. The Circuit Court, on demurrer, held the plea to be a good defense to the action on the bond.

We entertain no doubt as to the incorrectness of this ruling. The purpose of the act approved March 17th, 1875, which is embodied in sections 164 to 168, inclusive, of the Code, is manifest. It was designed to destroy the evil of straw-bonds, which had formally years previous prevailed in this State, during which one person, often himself a bonded officer of the Federal Government, or of the State, or of a county or municipality, was surety on a score of bonds of as many different officials, many of whom frequently interchanged the favor of mutual suretyship. These bonds were insufficient, by reason of the multiplied contingent liabilities of the obligors; and the non-residence of the parties was a stumbling block to a diligent inquiry by the approving officer as to their sufficiency. — Ex parte Buckley, 53 Ala. 42. The title of the act is declared to be, “ To secure good and sufficient sureties upon the bonds of the county officers of this State.” — Acts 1874-75, p. 50. We must construe the act with reference to the mischief and defect against which the previous law did not provide, and the nature of the remedy appointed to correct them; so, in other words, as to meet the mischief, and to advance the remedy, and, in doing so, not to violate fundamental principles. — -Potter’s Dwarris Stat. & Const. 184. To this end, being a remedial statute, it must be largely as beneficially construed. — Steele v. Tutwiler, 68 Ala. 107; Ex parte Buckley, supra.

*102We are satisfied that the legislative intent was never, in view of the foregoing considerations, to declare a bond of no binding efficacy on the obligors because of their insufficiency as sureties under the requirements of the statute. The language of the statute is, that the bond “shall be invalid and insufficient” but this does not mean for' all and every purpose. It meáns simply for the purposes of the act. The word “ invalid ” is narrowed in meaning by the context and the policy of the statute, the sixth section of which, now comprising section 192 of the Code, authorizes the chancellor of the division, or circuit judge of the circuit, on application to them, by five or more resident freeholders of the county, properly verified by affidavit, to pronounce any bond of the officers designated to be “invalid or insufficient” for want of conformity to the requirements of the act, and thereupon to require the execution of a new bond with sufficient sureties. — Code, 1876, § 192; Acts 1874-75, p. 51, sec. 6. It has never been supposed that the want of the requisite statutory qualifications on the part of a surety upon an official, or other bond, exempted either himself or his co-obligors from all liability upon such bond. Such surety is estopped, upon every principle of fair dealing and good conscience, from asserting his own disqualification as a defense to such liability, because the signing of the bond was an admission to the contrary, and he can not afterwards work an injustice by seeking to gainsay it. The policy of the law would be defeated by adopting a construction which would admit of a result so inequitable, and we would be confronted by the absurdity that all bonds of the class under discussion would be void for all purposes, and of no binding force on the obligors, if any one of them, by concealment, misrepresentation or artifice, could procure himself to be accepted as an approved surety, when, in truth and fact, he was insufficient under the provisions of this statute, because of his non-residence in the county, or other unknown disqualification. To state such a proposition is to refute it.

The ruling of the Circuit Court was erroneous, and the judgment is reversed and the cause remanded.
