A California appeal court on Wednesday upheld a sanction of more than $6,600 after finding that the plaintiffs in a property dispute had engaged in “gamesmanship” in a deliberate effort to bog down discovery.

“We have no difficulty in affirming the trial court’s determination that in this case plaintiffs forced to court a dispute that was not ‘genuine,’” Justice J. Anthony Kline wrote for San Francisco’s 1st District Court of Appeal.
