Appellants Dennis Patrick and Vince Garcia (“Plaintiffs”) sued the former sheriff of Sterling County, Don Howard, and others 1 (“Defendants”) for tort damages arising from their alleged wrongful criminal prosecution. Defendants moved for summary judgment on the ground that the applicable statutes of limitations barred the claims. See Tex.Civ. Prac. & Rem.Code Ann. §§ 16.002, .003 (West 1986). The trial court granted the motion and rendered a take-nothing judgment for Defendants. Plaintiffs appeal, contending that the trial court improperly granted summary judgment because either the discovery rule or the doctrine of fraudulent concealment tolled the statutes of limitations. We believe that neither is applicable in this context and will therefore affirm the trial-court judgment.
FACTUAL AND PROCEDURAL BACKGROUND
Garcia and Patrick were subjects of an undercover drug operation instigated by the Sterling County Sheriffs Department. Both were indicted for drug offenses. Garcia was acquitted by a jury on August 14,1990. The criminal indictment against Patrick was dismissed on April 29,1991. On August 9,1993, well in excess of two years following the termination of their criminal prosecutions, Plaintiffs filed suit against Defendants alleging: conspiracy, wrongful procurement of criminal complaints, false swearing, false arrest, false procurement of arrest, unreasonable search and seizures, false imprisonment, intentional infliction of emotional distress, invasion of privacy, conversion of personal property, abuse of process, and malicious prosecution.
The thrust of their complaint was that Defendants relied on an informant, William Lonnie Hood, who was himself later convicted of perjury in connection with other arrests and prosecutions. Plaintiffs allege that Defendants failed to use proper police procedures in creating and implementing their “sting” operation, thereby tortiously harming them in violation of the common law, Texas Tort Claims Act, and Texas Constitution. Additionally, Plaintiffs contend that Defendants knew Hood had fabricated evidence, *943 committed penury, and falsely accused them, yet fraudulently concealed these facts from them.
Defendants moved for summary judgment on the ground that limitations barred all of Plaintiffs’ claims. 2 Plaintiffs did not file a response to the summary judgment motion. Rather, they moved for a continuance because discovery was in its early stages. 3 At a hearing on November 1, 1993, the trial court denied the Plaintiffs’ continuance motion. The trial court later granted Defendants’ summary judgment motion and rendered a take-nothing judgment in their favor. In three points of error, Plaintiffs contend on appeal that the trial court erred in granting the summary judgment because: (1) material fact issues exist regarding the discovery rule and fraudulent concealment; (2) the trial court improperly relied on Plaintiffs’ failure to file a response to the summary judgment motion; and (3) the trial court abused its discretion in denying their motion for continuance.
DISCUSSION
We review the summary judgment under the well-established standards expressed in
Nixon v. Mr. Property Management Co.,
A. Statutes of Limitations
Plaintiffs’ malicious prosecution claim is controlled by the one-year statute of limitations.
See
Tex.Civ.Prac. & Rem.Code Ann. § 16.002 (West 1986). The remainder of Plaintiffs’ personal injury and property claims are governed by a two-year limitations period.
See
Tex.Civ.Prac. & Rem.Code Ann. § 16.003(a) (West 1986) (“A person must bring suit for trespass for injury to the estate or to the property of another, conversion of personal property, taking or detaining the personal property of another, personal injury, forcible entry and detainer, and forcible detainer not later than two years after the day the cause of action accrues.”);
see also Vale v. Ryan,
Plaintiffs’ malicious prosecution claims accrued upon the termination of the criminal prosecutions.
See McHenry v. Tom Thumb Page Drug Stores,
Defendants’ summary-judgment evidence proved that Garcia’s criminal prosecution terminated with his acquittal on August 14, 1990. Patrick’s criminal prosecution terminated when the criminal indictment against him was dismissed on April 29, 1991. Plaintiffs’ own pleadings allege they were innocent of these criminal charges. Hence, Plaintiffs knew of all of their injuries, at the latest, when their criminal prosecutions ceased. 4 Plaintiffs delayed filing suit, however, until August 9, 1993, well in excess of two years after their respective criminal prosecutions had terminated. Consequently, Defendants satisfied their initial burden of demonstrating conclusively that Plaintiffs’ claims are barred by the applicable statutes of limitations. Nonetheless, Plaintiffs contend in their third point of error that the trial court erred in granting summary judgment because either the discovery rule or fraudulent concealment tolled limitations. We conclude that neither doctrine applies in the circumstances of the present case.
B. Discovery Rule
Plaintiffs allege that the discovery rule applies to their claims because they were unaware of the facts forming the basis of their claims until December 18, 1992, when William Lonnie Hood was convicted of perjury in connection with another case. We disagree.
The discovery rule is an exception to the general rule of accrual.
Moreno,
Plaintiffs’ tort claims stemming from wrongful criminal prosecution satisfy neither prong of the test. The nature of Plaintiffs’ injuries is not inherently undiscov-erable. Plaintiffs’ pleadings assert that they were innocent of all criminal charges against them. Thus, by their own admission, Plaintiffs knew of their alleged injuries when they were falsely arrested, detained, and prosecuted. Plaintiffs’ assertion that they did not know of all the facts surrounding their injuries until Hood’s perjury conviction does not trigger the discovery rule. A party’s ignorance of material facts or lack of knowledge does not generally prevent limitations from running.
Snyder,
C. Fraudulent Concealment
Plaintiffs also allege that the doctrine of fraudulent concealment tolls the running of limitations. Plaintiffs contend that Defendants knew of Hood’s misconduct but concealed the facts that formed the basis of their lawsuit. Consequently, Plaintiffs conclude that Defendants should be estopped from relying on the limitations defense. Again, we disagree.
Fraudulent concealment is an equitable doctrine that, when properly invoked, estops a defendant from relying on limitations as an affirmative defense.
Borderlon v. Peck,
Where a defendant is under a duty to make disclosure but fraudulently conceals the existence of a cause of action from the party to whom it belongs, the defendant is estopped from relying on the defense of limitations until the party learns of the right of action or should have learned thereof through the exercise of reasonable diligence.
Borderlon,
The issue of whether a duty of disclosure exists is a question of law for the court.
Seibert,
Defendants pleaded and proved that Plaintiffs failed to bring suit within the applicable limitations periods. Because neither the discovery rule nor fraudulent concealment applies, the trial court did not err in granting summary judgment based on lim *946 itations. We overrule points of error two 6 and three.
D. Continuance
Plaintiffs’ first point of error asserts that the trial court abused its discretion when it denied Plaintiffs’ motion for continuance. They contend that because the case had been on file for only three months and discovery was in its early stages, the trial court should have granted their motion. Plaintiffs rely on
Levinthal v. Kelsey-Seybold Clinic,
Of these factors, only the three-month time frame is comparable to the present ease. Plaintiffs claim the discovery was material because it would yield evidence to support the applicability of the discovery rule and fraudulent concealment. However, because as a matter of law neither of these doctrines applies here, no amount of additional discovery could bolster Plaintiffs’ position. Likewise, Plaintiffs’ submission of excessive interrogatories in violation of the Texas Rules of Civil Procedure, duplicative sets of discovery, and voluntary withdrawal of the initial requests do not mirror the diligence that the plaintiff exercised in Levinthal. We conclude that the trial court did not abuse its discretion in denying Plaintiffs’ motion for continuance. Point of error one is overruled.
CONCLUSION
Defendants properly pleaded and proved that Plaintiffs’ claims were barred by the statutes of limitations. While Plaintiffs raised the discovery rule and fraudulent concealment in an attempt to defeat the affirmative defense of limitations, as a matter of law these doctrines do not apply. Therefore, the trial court did not err in granting summary judgment for the Defendants on limitations grounds. Having overruled all points of error, we affirm the trial court’s judgment.
Notes
. Other defendants included County Commissioners Johnny Hughes, Russell Noletubby, and Melvin Foster, County Judge Robert Browne, the Office of the District Attorney, and Sterling County. Plaintiffs also named police informant William Lonnie Hood as a defendant in the lawsuit. However, Hood’s whereabouts were unknown, and service of process was never completed on him.
. Defendants also moved for summary judgment on the basis that there are no private causes of action for damages under the Texas Constitution. In
City of Beaumont v. Bouillion,
. Plaintiffs submitted their first set of interrogatories on September 29, 1993. This set contained well in excess of the maximum thirty questions, including subparts, that are permitted by the Rules of Civil Procedure. See Tex.R.Civ.P. 168(5). Plaintiffs then submitted a second set of interrogatories and a request for production on October 13, 1993. Likewise, this second set of interrogatories exceeded the thirty-question limit. Following the second request, Plaintiffs entered into a voluntary Rule 11 agreement withdrawing the first set of interrogatories. At the time of the November 1, 1993 summary-judgment hearing, therefore, Defendants had not responded to the discovery requests since their response was not due until mid-November.
. Plaintiffs, of course, knew of many of their alleged injuries well before the termination of the criminal prosecutions. For example, they knew of their injury from false arrest at the time of arrest. For simplicity, we analyze the limitations issue using the latest possible date.
. Rather than presenting an appropriate case for application of the discovery rule, Plaintiffs’ situation reaffirms the purpose of statutes of limitation: to assert a claim while the evidence is fresh in the minds of parties and witnesses. In this *946 case, a vital player, police informant Hood, is missing, and his whereabouts are unknown.
. Plaintiffs' second point of error alleges the trial court erred because it based summary judgment on Plaintiffs' failure to file a response to the summaiy-judgment motion, rather than on Defendants’ motion and summary-judgment evidence. Specifically, Plaintiffs argue that Defendants did not present any evidence defeating the discovery rule or fraudulent concealment. However, Defendants were only required to present evidence negating the discovery rule
if
it applied to Plaintiffs’ claims.
