It is contended by the defendants that the direction of a verdict against them was error because it had become the law of the case that one of their defenses, which was supported by uncontradicted evidence, demanded a verdict in their favor, in that a demurrer to that defense had been overruled and no exceptions preserved to such ruling. In Story v. First National Bank of Thomson, 34 Ga. App. 27 (128 S. E. 12), it is held: “Where a general demurrer to a plea is overruled and no exception to this ruling is taken, the ruling becomes the law of the case and 'stands as a solemn adjudication that the plea was good.’ Bennett v. Simmons, 30 Ga. App. 531 (118 S. E. 494), and citations. Where, on the trial of such a case, the defendant introduces evidence which substantially supports her plea, even though the plaintiff introduces conflicting evidence, it is error for the judge to direct a verdict for the plaintiff. Pierpont Mfg. Co. v. Mayor &c. of Savannah, 153 Ga. 455, and cases cited on pages 457 and 458 (112 S. E. 462); Vickery v. Swicord, 151 Ga. 145 (106 S. E. 92).”
Paragraph 15 of the answer contained a special defense as follows: “As a further and alternative defense, defendants allege that the plaintiff has not heretofore obtained judgment against the contractor, A. T. Wheeless, for the price of the materials as to which the plaintiff’s lien is asserted and further show that the judgment referred to in paragraph 6 of the plaintiff’s petition, as amended, is not a judgment for the price of such materials but is a judgment on the note executed under said contract of April 10, 1951, as alleged above.” A demurrer was interposed to this defense on the ground that the allegations “are irrelevant and immaterial in that an express judgment for the price of materials is not necessary, but a judgment which includes the purchase price for the materials which have gone into the property of the defendants is sufficient to authorize a lien upon defendants’ property.” The overruling of this demurrer established as the law of the case that this defense was material, in that an express judgment for the price of materials must be shown in order to comply with the provisions of Code (Ann. Supp.) § 67-2002 (3), rather than a judgment on a note which includes the purchase price of the materials. The proof demanding a finding that the materialman’s judgment against *512the contractor, which was a condition precedent to the foreclosure of his lien, was not such an express judgment for the price of the materials—a finding was demanded, under the law of this case, that the plaintiff had failed to comply with the statutory conditions relative to foreclosure, and was therefore not entitled to a judgment in its favor. The trial court therefore erred in denying the motion for new trial, which specifically urged this defense. •
A defendant is entitled to file as many separate defenses as he desires, regardless of whether such defenses are inconsistent or contradictory. Code §'81-310; Associated Mutuals v. Pope Lumber Co., 200 Ga. 487 (1) (37 S. E. 2d 393). It follows, therefore, that a “further and alternative defense” set up by the defendants in paragraph 13 of their answer neither helped nor hindered the separate defense contained in paragraph 15 above referred to. For this reason the demurrer directed to the defense contained in paragraph 15 pertained to this defense alone, and the judgment overruling this demurrer did not, as contended by the defendant in error, have any relation to paragraph 13 so as to prevent the defense set out in paragraph 15 from becoming the law of the case.
Nor can it be contended that the judgment of the trial court in overruling a special demurrer to paragraph 6 of the amended petition is contradictory to what is here held. Although paragraph 6 alleged that the plaintiff had obtained a judgment against the contractor for $3,056.69, “which principal amount included the amount of $496.56 for materials sold and used in the improvement of defendants’ property,” the demurrer was based solely on the ground that no copies of the pleadings or judgment in that case were attached to the petition. Such a judgment is a condition precedent to recovery against the property owner, under the provisions of Code (Ann. Supp.) § 67-2002, but it is not the cause of action, nor the basis of the relief prayed, in such manner as to make it necessary to set out the pleadings, evidence, or judgment of such former suit in the foreclosure proceedings. Code § 81-105; Simpson v. Charters, 185 Ga. 592 (2) (196 S. E. 31). It was not error to overrule this ground of demurrer.
*513The trial court erred in denying the motion for new trial for the reason set out in the first division of this opinion.
Judgment reversed.
