The opinion of the Court was delivered by

This is an action on open account for goods (ladies’ dresses) sold and delivered to defendants. Plaintiff alleged that the goods were reasonably worth $290.00, and that defendants were indebted to him in that amount for them. The answer was a general denial. At the trial defendants offered to prove that the goods were defective in material and workmanship. The evidence was excluded as inadmissible under the general denial. Defendants then asked leave *543 .to amend their answer to conform to the facts adduced. The -motion was refused, and a verdict was directed for plaintiff for the full amount sued for.

1 The evidence offered was clearly admissible under the general denial to disprove plaintiff’s allegation of value. It was not an affirmative defense, by way of confession and avoidance, but went to disprove a material allegation of the complaint. Lyles v. Bolles, 8 S. C. 258; McElwee v. Hutchinson, 10 S. C. 436; Pom. Rem., sec. 673, et seq. The case of Derry v. Holman, 27 S. C. 621, 2 S. E. 841, relied upon by respondent, is not in point, because that Was an action on a note, which prima facie imports a consideration, and it was properly held that failure of consideration was new matter, which could not be proved under a general denial. Pom. Rem., sec. 709.

2 In this view of the case, it is, perhaps, unnecessary to consider the assignment of error in refusing defendants’ motion to amend, except in so far as the evidence offered tended also to prove that defendants had attempted tQ rescind the contract by returning part of the goods and tendering payment for the part retained. This, of course, was new matter, constituting an affirmative defense, evidence of which was inadmissible under the general denial; and therefore, if defendants intended to rely upon that defense, they could not have done so,- without amending their answer.

While amendments are largely in the discretion of the trial Court, that discretion should not be arbitrarily exercised, either in granting or refusing such motions, but it should be exercised so as to prevent surprise and promote justice, especially-since the Court may impose “such terms as may be proper,” and ordinarily thereby provide against unjust consequences.

*544 3 *543 It is not clear whether the amendment was refused because the trial Judge thought he had no power to allow it, or *544 because lie did not think its allowance would be a proper^ exercise of his discretion. In response to the motion he merely said: “I cannot allow an amendment at this time.” It is needless to cite authority to show that the Court had power to allow the amendment at that stage of the trial, even though it might have been necessary to withdraw the case from the jury and continue it, to prevent prejudice to the opposite party. Koennecke v. Railway, 101 S. C. 86, 85 S. E. 374.

4 If, on the other hand, it was refused in the exercise of the Court’s discretion, we are not prepared to say that it was so clearly an erroneous exercise of discretion as to warrant the interference of this Court, especially as defendants did not make it clear to the Court what amendment they wanted, whether it was merely to the extent necessary to let in the evidence, offered to reduce the amount that plaintiff might recover as the value of the goods, or to defeat his action entirely under the claim that the sale had been rescinded. If the former, it was unnecessary, as we have said; if the latter, it may have been properly refused at that stage of the trial, in the absence of any showing by defendants of surprise; that is, that they really intended to make that defense, and honestly believed their answer sufficient to admit evidence to support it.

Judgment reversed.
