¶1 Appeal from judgment of dismissal. Appellant sought recovery for property damage to his automobile. He alleged his insurer, St. Paul Fire & Marine Insurance Company, had paid him the amount of his damages except $50 deductible under a policy of collision insurance; that the insurer thereby became subrogated to this extent, and under the terms of the policy was entitled to assert its cause of action in his name; that the damages were proximately caused by defendant’s negligence.
¶2 Appellee filed an unverified plea alleging that on a date nearly one month after the suit was filed, plaintiff executed a release discharging defendant from all liability for property damage. Appellant then pleaded that appellee had full notice of the subro-gation interest of the insurer before he executed the release. Appellee’s allegations of the terms of the release were embodied in an unverified pleading termed a “motion to dismiss.” The court granted the motion and dismissed the action by virtue of the pleaded release.
¶3*848 The court was not authorized to summarily dispose of the action on a plea in bar.
¶4 This was not a summary judgment proceeding under Rule 166-A, Texas Rules of Procedure. If it could be considered such, plaintiff’s pleadings would have precluded summary judgment. A release by appellant given to appellee with notice of the subrogation rights does not affect or prejudice the rights of the insurer. Wichita City Lines v.
