assigned courthouse duty, and Donoho replied that Zimlieh was “lucky to have a job after the [Peters] incident.” Four months after Zimlieh returned to the Marshal’s Office, Donoho conducted an annual performance evaluation for Zimlieh. Prior to his SWEEP duty, Zimlich’s superiors had always commended him for his superior performance and evaluated him as above average. Zimlich’s evaluation after he returned to the Marshal’s Office, however, was significantly lower. Donoho rated Zimlieh as average and noted that Zimlieh was not a team player and that he needed to accept his job assignments willingly. Zimlieh officially noted his disagreement with his evaluation.
After eight months on courthouse security duty, Donoho assigned Zimlieh to his preferred position in the warrants division. Later, a senior deputy position became available in the department. Zimlieh applied for the position, and was interviewed for the job along with five other candidates, but he was not promoted. Donoho was one of the three members of the panel that made the promotion decision. In the summer of 1995, Donoho retired and was replaced by Marshal Rutledge. Within several months, Zimlieh was promoted to senior deputy. Soon after, a position for chief deputy became available. Zimlieh applied for this position, but was not promoted.
Based on this evidence, the jury concluded that the City discriminated against Zimlieh with malice in retaliation for reporting Davis’s illegal obstruction of an official investigation. The jury awarded $200 for lost earnings in the past, $300,000 for lost earnings in the future, $800,000 for mental anguish, and $1,500,000 in punitive damages. The City appealed, and the court of appeals affirmed the trial court’s judgment. 975 S.W.2d at 415. The City now petitions this Court for review.

Discussion
The City raises several issues on appeal. First, the City contends that it cannot be liable under the Whistleblower Act since there is no evidence that the City discriminated against Zimlieh. Second, the City argues that there is no evidence of malice to support the punitive damages award. The City also challenges whether venue was proper, whether the jury charge was supported by the pleadings, and whether Zimlieh made admissions inconsistent with the judgment. We address each of these issues in turn.
A
A governmental entity is liable for damages under the Whistleblower Act if it discriminates against a public employee who reports a violation of law. See Tex. Gov’t Code §§ 554.001-.009 (Supp.2000). The statute in force at the time of the alleged discrimination against Zimlieh provides: “A state agency or local government may not suspend or terminate the employment of or discriminate against a public employee who in good faith reports a violation of law to an appropriate law enforcement authority.” Act of May 22, 1993, 73rd Leg., R.S., ch. 268, § 1, 1993 Tex. Gen. Laws 583, 610 (amended 1995) (current version at Tex. Gov’t Code § 554.002) (Supp.2000). While the statute does not explicitly require an employee to prove a causal link between the report and the subsequent discrimination, we held in Department of Human Servs. v. Hinds, 904 S.W.2d 629, 633 (Tex.1995), that the employee must demonstrate all elements of the action, including causation, by a preponderance of the evidence. To show causation, a public employee must demonstrate that after he or she reported a violation of the law in good faith to an appropriate law enforcement authority, the employee suffered discriminatory conduct by his or her employer that would not have occurred when it did if the employee had not reported the illegal conduct. See Hinds, 904 S.W.2d at 633.
Zimlieh contends that he reported a violation of the law to the appropriate
