I agree with attorney Brinkmeier. You should have sent notice of the subpoena to the other side, thus giving them an opportunity to object to the subpoena, but the judge may overlook your oversight..
Is there a Supreme Court Rule or provision in the Code of Civil Procedure that requires notice? Sat in court this morning, heard a lawyer chastised by the judge for issuing subpoena without notice to the other parties. The lawyer, who appeared to be an experienced litigator, replied, "there is no such rule." The judge, very experienced herself, responded: Really? And then entered an order that no further subpoenas issue without notice (citing her authority to regulate discovery) but was not able herself, to point to any such rule. Does any lawyer know the Answer? I do not. www.galivanlaw.net
