Defendant denied requests for admission that certain hospital records were authentic and business records.  This decision holds that the trial court erred in failing to award plaintiff the cost of proving the records were business records under CCP 2033.420. The trial court erred in denying those costs on the ground that plaintiff did not prove the records were business records “at trial.”  The section doesn’t require proof “at trial.”  Here, the proof was offered in support of a successful motion in limine to admit the records.  And, defendant’s “concession” after the motion in limine was granted didn’t protect him from sanctins either.  Nor was the mere hope that plaintiff would fail to prove the records to be business records (as she had at a prior trial) a reasonable ground for denying the request for admission.
