If the court of appeals determines that an appeal is frivolous, it may - on motion of any party or on its own initiative, after notice and a reasonable opportunity for response - award each prevailing party just damages. In determining whether to award damages, the court must not consider any matter that does not appear in the record, briefs, or other papers filed in the court of appeals.
Tex. R. App. P. 45
