In Matter of Johnson v. Crane (171 AD2d 537, 539 [1st Dept 1991]), the court held a bail-setting court has "substantial discretion" in determining whether or not to conduct an inquiry into the source of bail collateral, and that such a court should not feel limited to the matters expressly put forth in subdivision (1) of CPL 520.30. Therefore the fact that CPL 520.30 (1) does not specify strangers posting bail as an enumerated reason to conduct a surety hearing does not preclude the court from doing so, if it determines that such a result could contravene public policy.
