Power to reject sureties requires an inquiry, notice, evidence recording and stated reasons before rejection. A Magistrate may refuse to accept or may reject any surety on the ground that the surety is an unfit person; before doing so the Magistrate must hold or cause an inquiry on oath, give reasonable notice to the surety and the person who offered the surety, record the substance of the evidence, consider any report from a subordinate Magistrate, and, if rejecting a previously accepted surety, issue a summons or warrant to bring the principal before him and record reasons for the rejection.
