What is the test for sealing a search warrant?

The court must first determine whether sufficient grounds exist for maintaining the confidentiality of the informant's identity. The court should then determine whether the extent of the sealing of the affidavit or any major portion thereof is necessary to avoid revealing the informant's identity. (People v.
