OPINION
Belinda Moore Rogers appeals a judgment entered against her for property damage to the Stells’ car. In four points of error, Rogers contends that the trial court erred in failing to grant her motion for instructed verdict and in not allowing her to testify. We overrule Rogers’s points of
PROCEDURAL HISTORY
Belinda Rogers’s and Mary Stell’s cars collided on a frontage road as Rogers attempted to enter an expressway. The Stells sued Rogers for the property damage to their car. She answered with a general denial. The Stells served discovery requests on Rogers. One interrogatory asked for the name and address of any witness that she intended to call to testify. She responded “permitted” but objected to the production of documents and to the question as being “excessively burdensome, unnecessary expense, and a harassment to this defendant.” She did not give any names of witnesses in response to that interrogatory. She also objected to eighteen other interrogatories. A hearing was set on the objections. Rogers did not appear at that hearing. The trial court overruled all the objections.
Rogers never answered or supplemented her answers to the interrogatories. When Rogers’s counsel called her as a witness at trial, the Stells objected on the grounds that she was never named as a witness in response to the interrogatory. The trial court sustained the objection and refused to let her testify. The court then entered judgment in the Stells’ favor.
INSTRUCTED VERDICT
In her first point of error, Rogers contends that the trial court erred in failing to grant her motion for instructed verdict. An instructed verdict is proper when there is no evidence of probative force to raise a material fact question. See Qantel Business Sys., Inc. v. Custom Controls Co.,
DISCOVERY REQUESTS
In her second, third, and fourth points of error, Rogers contends that the trial court erred by refusing to let her testify. She argues that the trial court’s ruling prevented her from putting on any evidence, that the trial court abused its discretion, and that the rules do not authorize this sanction.
The Stells initially presented Rogers with an improper interrogatory when they asked for the names of witnesses that she intended to call at trial. See Alvarado v. Farah Mfg. Co., 34 Tex.Sup.Ct.J. 107, 109 (Nov. 24, 1991); Gutierrez v. Dallas Indep. School Dist.,
Paragraph 5 of Texas Rule of Civil Procedure 215 provides:
A party who fails to respond to or supplement his response to a request for discovery shall not be entitled to present evidence which the party was under a*117 duty to provide in a response or supplemental response or to offer the testimony of an expert witness or of any other person having relevant knowledge of discoverable matter, unless the trial court finds that good cause sufficient to require admission exists. The burden of establishing good cause is upon the party offering the evidence and good cause must be shown in the record.
Pretrial discovery proceedings have as their aim and purpose the administration of justice by allowing the parties to obtain fullest knowledge of issues and facts prior to trial. See Alvarado, 34 Tex.Sup.Ct.J. at 109. By requiring complete responses to discovery, rule 215 promotes responsible assessment of settlement and prevents trial by ambush. Id. The trial court has discretion to determine whether the offering party has met the burden of showing good cause for admission of the testimony. However, the trial court has no discretion to admit testimony excluded by the rule without a showing of good cause. The rule is mandatory and the sanction automatic. Id. The Texas Supreme Court consistently looks to whether the responding party showed good cause for failure to supplement discovery as being “good cause sufficient to require admission.” Id. at 108; Tex.R.Civ.P. 215(5).
The Houston and Amarillo courts have considered this issue. See Smith v. Southwest Feed Yards, Ltd.,
In Miller, the trial court permitted Bynum to testify as a fact witness, but not as an expert witness. Miller,
The Amarillo Court declined to follow Miller and Jandl. Smith,
The Texas Supreme Court has not yet directly considered the question of an undisclosed party witness.
The Texas Supreme Court continually emphasizes that parties must “lay their cards on the table” to facilitate the evaluation of the real risks of trial and the possibilities of settlement. Alvarado, 34 Tex. Sup.Ct.J. at 110. Lawsuits are not always between individuals, but may involve classes, multiple parties, or entities such as corporations and partnerships. See Smith,
We hold that a party to an action is required to be identified in response to an authorized discovery request and is subject to the rule 215 sanction unless the party shows good cause for failure to respond or to supplement responses. The only evidence Rogers urged to satisfy the good cause exception was her status as a party. The trial court did not abuse its discretion by failing to find that Rogers’s status as a party was sufficient good cause. Absent a showing of good cause, the trial court had no discretion to admit Rogers’s testimony and, therefore, properly excluded it.
We overrule Rogers’s second, third, and fourth points of error. We affirm the trial court’s judgment.
Notes
. The Texas Supreme Court has granted writ in the Miller case on Miller's complaint that the court of appeals erred in affirming the trial court’s decision to allow an unidentified witness, the party plaintiff, to testify. 34 Tex.Sup.Ct.J. 408. Further, the writ denied on the Jandl case does not denote the Texas Supreme Court’s affirmance of the Houston Court’s reasoning. Smith,
