In what circumstances will a court deny a Petitioner's request for a Personal Rights Review?

In this case, the trial court identified three apparent reasons for its denial of the PRA petition, including that petitioner filed suit without communicating to real party that she thought it had not disclosed all responsive documents, that there was no evidence of willful or intentional withholding of documents, and that the categories in petitioner's PRA were "vague and unclear." Real party, either expressly or impliedly, relies on these same reasons in its opposition to the writ petition. We have found authority for the proposition that a PRA request "must itself be focused and specific" (Rogers v. Superior Court (1993) 19 Cal.App.4th 469, 481), and we address petitioner's compliance with this rule for most of the remainder of this opinion.
