OPINION
OSBORN, Justice.This is a venue case in which it is alleged that the Appellant intentionally shot and killed Ben Baxter Ingham, III, in Terrell County, and that venue may be maintained in that county under subdivision 9 of Article 1995, Tex.Rev.Civ.Stat., in this suit by his heirs and estate. The trial court overruled Appellant’s plea of privilege. We reverse and order the case against Leonard Liveoak transferred to Bexar County, Texas.
After suit was filed, Leonard Liveoak filed a plea of privilege and a general denial. The evidence establishes that Leonard Liveoak did shoot and kill Ben Baxter Ing-ham, III, in Terrell County on September 23, 1981. The evidence indicates that Mr. Liveoak, at the time, claimed a justification for his conduct in that he said on several occasions that Mr. Ingham was choking him and trying to kill him.
The first point of error contends the shooting was done with justification and in *568self-defense, and that there is no evidence of an unlawful act which would establish a crime or trespass in Terrell County. Appellant argues that when evidence of justification is raised in a criminal case, the State must prove beyond a reasonable doubt that the killing or assault was not done in self-defense and was not justified. See: Section 9.31 and 9.32, Tex.Penal Code; Luck v. State, 588 S.W.2d 371 (Tex.Cr.App.1979). He concludes that the evidence from Appel-lees’ own witnesses establishes that no crime was committed because his own conduct was justified. The Appellees reply that this is a defensive issue which was not raised by the pleadings and that, in any event, the court is not concerned with defensive issues when it only decides venue of a case.
The court in Foster v. H.E. Butt Grocery Co., 548 S.W.2d 769 (Tex.Civ.App.—San Antonio 1977, writ ref’d n.r.e.), discussed each of these contentions. That is a venue case in which the court considered the question of whether self-defense in an assault case was an affirmative defense and therefore immaterial in a venue case, or whether it was an issue related to the plaintiff’s prima facie case. In rejecting the affirmative defense contention, Chief Justice Barrow, writing for the majority of the court, said:
A similar contention was considered and rejected by the Supreme Court in Grieger v. Vega, 153 Tex. 498, 271 S.W.2d 85 (1954). This was a suit for damages for wrongful death wherein the Court was required to decide the question of which party had the burden of proof where the evidence raised self-defense. The Court recognized at the outset that the authorities were conflicting on this question. It is clear from the opinion that Vega vigorously relied on the holding of Cameron Compress Co. v. Kubecka, 283 S.W. 285 (Tex.Civ.App.—Austin 1926, writ ref’d). After a full review of the authorities, it was held that if plaintiff proved an intentional killing, he has met his burden of showing that the death was wrongful. However, if the evidence raises an issue of justification, such as self-defense, the plaintiff has the burden of proof to overcome the evidence of self-defense. Otherwise, plaintiff fails to prove his cause of action that the death was wrongful. This holding was followed in Bradford v. Fort Worth Transit Company, 450 S.W.2d 919 (Tex.Civ.App.—Fort Worth 1970, writ ref’d n.r.e.). See also McMurrey Corp. v. Yawn, 143 S.W.2d 664 (Tex.Civ.App.—Texarkana 1940, writ ref’d).
It would seem from that holding that self-defense is in the nature of an inferential rebuttal issue. Norris v. Branham, 557 S.W.2d 816 (Tex.Civ.App.—El Paso 1977, writ ref’d n.r.e.). Such issues are ones which require affirmative pleading and some evidence raising the particular theory which is inconsistent with the plaintiff’s theory for recovery. In such cases, the burden of proof is on the plaintiff to establish the nonexistence of the rebuttal issue. Hodges, Special Issue Submission in Texas, Section 17 (1959).
In this case, the evidence certainly raised the issue. Not only that, it was part of the plaintiff’s evidence, and having offered that part of the deposition of Ronald D. Eckhart which raised the issue, the plaintiff is bound by such evidence. Polasek v. Quinius, 438 S.W.2d 828 (Tex.Civ.App.—Austin 1969, writ ref’d n.r.e.); Ballard v. Aetna Casualty and Surety Company, 391 S.W.2d 510 (Tex.Civ.App.—Corpus Christi 1965, writ ref’d n.r.e.).
In this case, the plaintiff offered no evidence to overcome the proof establishing a justification for the killing of Mr. Ingham. Thus, there was no proof which would have permitted the trial court to find the claim of justification did not exist. And since the plaintiff was bound by such proof, the court was obligated to find the justification was established and the plaintiff had not proven a crime or a trespass, since the latter arises from “wrongful acts,” and if there was a justification for the killing, there was no “wrongful act.” Reaves v. Brooks, 430 S.W.2d 926 (Tex.Civ.App.—Amarillo 1968, writ dism’d).
*569In our case, the defendant’s answer contains only a general denial. Inferential-rebuttal theories require affirmative pleadings to raise the issues, and a general denial will not suffice. Cooper v. Boyar, 567 S.W.2d 555 (Tex.Civ.App.—Waco 1978, writ ref’d n.r.e.); Salley v. Black, Sivalls & Bryson, 225 S.W.2d 426 (Tex.Civ.App.—San Antonio 1949, writ dism’d); Hodges, supra. But, issues which require an affirmative pleading may be tried by consent, in which case, a failure to amend the pleading to conform to the evidence does not affect the result of the trial on such issues. LaMarque Independent School District v. Thompson, 580 S.W.2d 670 (Tex.Civ.App.—Houston [14th Dist.] 1979, no writ); Whitley v. Whitley, 566 S.W.2d 660 (Tex.Civ.App.—Beaumont 1978, no writ). See also: Petroleum Anchor Equipment, Inc. v. Tyra, 419 S.W.2d 829 at 835 (Tex.1967). Since the plaintiff offered the evidence on the issue of the justification for the killing, there can be no question but that the issue was tried by consent. Point of Error No. One is sustained.
The last two points of error complain that the trial court erred in permitting Appellees to reopen their case after all parties had closed and in permitting the Appellees to offer additional evidence. It is also contended that there is no properly admitted evidence to establish that the Appellees are the heirs and executor of the estate of Benjamin Baxter Ingham, III. After the evidence was closed, the court raised a question about whether there was a stipulation on the heirship of the deceased. After some discussion, the court permitted counsel for Appellees to reopen and call a new witness who testified concerning heirship and, at the same time, counsel offered certified copies of instruments from the probate proceedings which showed that the Appel-lee, Jimmy Powers, had been appointed and qualified as independent executor of the deceased’s estate.
We conclude that there was no abuse of discretion in permitting one of the parties to reopen and offer additional evidence prior to the time the court ruled on the plea of privilege. The proof which was offered did establish that two of the Appel-lees herein are the surviving children of the deceased.
But, if we should be in error with regard to the court’s right to permit the Appellees to reopen and offer additional evidence, nevertheless, the issue as to the capacity of the parties to sue had not been raised by a verified pleading as required by Rule 93(b), Tex.R.Civ.P. In Ladner v. Reliance Corporation, 156 Tex. 158, 293 S.W.2d 758 (1956), the court said:
There are some situations in which the plaintiff is not required to prove all of his essential venue facts by independent evidence. Under our statutes and rules certain facts will be taken as admitted unless the defendant puts the same in issue by a verified pleading, and the plea of privilege does not constitute a verified denial of any allegation of plaintiff’s petition required to be denied under oath unless specifically alleged in such plea. See Rules 86 and 93, Texas Rules of Civil Procedure. When a venue fact is one which can be put in issue only by a verified pleading and the defendant does not interpose such a plea, the plaintiff is not required to prove the same.
Since the defendant in this case did not file a denial as to the capacity of the children or the independent executor to sue, their capacity as heirs and executor was admitted and no independent proof was required. Points of Error Nos. Two and Three are overruled.
The order of the trial court is reversed and the ease against Leonard Liveoak is ordered transferred to Bexar County, Texas.
