In Lemelle v. Superior Court (1978) 77 Cal.App.3d 148, the court declined to issue a peremptory writ because the defendant had failed to supply a record adequate to permit intelligent consideration of the lower court's exercise of discretion: "Just as an appellant must furnish an adequate record on appeal (see 6 Witkin, Cal. Procedure (2d ed. 1971) Appeal, 373, p. 4345 and cases there cited), a petitioner for an extraordinary writ to the trial court must furnish a record sufficient to enable the reviewing court to evaluate the lower court's exercise of discretion. The starting point of such a record is a copy of the order to be reviewed. A proper record should include a copy of all declarations filed in the lower court. It should in most instances also include a transcript of any hearing. In the absence of a transcript the reviewing court will have no way of knowing in many cases what grounds were advanced, what arguments were made and what facts may have been admitted, mutually assumed or judicially noticed at the hearing. In such a case, no abuse of discretion can be found except on the basis of speculation. That is the situation in the case at bench." (Pp. 156-157.)
