The following excerpt is from United States v. Mehciz, 437 F.2d 145 (9th Cir. 1971):
Assigning error to the trial court's refusal to supply the name of the informant at this stage of the prosecution, appellant relies on Costello v. United States, 298 F.2d 99 (9th Cir. 1962) for the broad proposition that "if the prosecution relies solely upon the tip of an informant as the sole justification for arrest, it must disclose the informant's identity."
