The trial court is not required to consider grounds for summary judgment that the movant’s papers do not identify, but the court may, in its discretion, consider an additional ground if an evidentiary basis for the additional ground appears in the summary judgment record, and (2) the opponent has notice of and an opportunity to respond to the additional ground.  Here, the moving papers obliquely referred to the additional ground that a co-defendant was not the movant’s ostensible agent.  The plaintiff responded to the ostensible agency issue in his opposition to the motion.  Plaintiff was not entitled to another opportunity to present additional evidence regarding agency before the trial court ruled on that ground.
