How will we proceed with questioning the expert witness in a personal injury case?

We will do so in the light of the issues framed by the complaint, ³ bearing in mind that he is an expert as well as a defendant and, therefore, may be asked for his opinions within the area of his competency. See Lawless v. Calaway, 24 Cal.2d 81, 89-91, 147 P.2d 604. In each instance we [148 Cal.App.2d 437] will undertake to determine whether the question is 'legal' and 'pertinent' even if the defendants interposed no objection of that nature at the time, the parties having stipulated that 'all objections propounded to the said witness shall be reserved by each of the parties, save and except any objections as to the form of the questions propounded. ⁴
