What is the effect of disclosing the identity of a confidential informant in a search warrant application?

The probable cause affidavit supporting the search warrant relied on information provided by a confidential informant. Trial counsel moved for disclosure of the informant's identity. The motion was denied because defendant was unable to establish that the informant's identity was material to the issue of defendant's guilt. (See People v. Lawley (2002) 27 Cal.4th 102, 159 ["the prosecution must disclose the name of an informant who is a material witness in a criminal case or suffer dismissal of the charges against the defendant"].) A briefing schedule was then set for a discovery motion related to the truthfulness of the affidavit under People v. Luttenberger (1990) 50 Cal.3d 1.
