What is the test for making a probable cause determination in an assault case?

As set forth in Gerstein v. Pugh, supra, 420 U.S. 103, 95 S.Ct. 854, a judicial determination of probable cause is only required where the state seeks to restrain an individual's liberty prior to trial. Even where a probable cause determination is required, the determination need not be "accompanied by the full panoply of adversary safeguards--counsel, confrontation, cross-examination, and compulsory process for witness." (Id., at p. 119, 95 S.Ct. at p. 866.)
