Section 21. Forfeiture of bond. - When the presence of the accused is required by the court or these Rules, his bondsmen shall be notified to produce him before the court on a given date and time. If the accused fails to appear in person as required, his bail shall be declared forfeited and the bondsmen given thirty (30) days within which to produce their principal and to show cause why no judgment should be rendered against them for the amount of their bail. Within the said period, the bondsmen must:
(a) produce the body of their principal or give the reason for his non-production; and
(b) explain why the accused did not appear before the court when first required to do so.
Failing in these two requisites, a judgment shall be rendered against the bondsmen, jointly and severally, for the amount of the bail. The court shall not reduce or otherwise mitigate the liability of the bondsmen, unless the accused has been surrendered or is acquitted. (21a)
