Does appellant's failure to brief on vexatious litigant order constitute a waiver or abandonment of the issue on appeal?

Neither appellant's opening brief nor his reply brief address the trial court's vexatious litigant order. We therefore find appellant has abandoned his appeal of this order. (Behr v. Redmond (2011) 193 Cal.App.4th 517, 538 [appellant's "failure to brief the . . . issue constitutes a waiver or abandonment of the issue on appeal"].)

The orders are affirmed. Respondent is awarded his costs on appeal.
