Swiss Criminal Procedure Code
(Criminal Procedure Code, CrimPC)

¹ The court shall al­low the pub­lic pro­sec­utor the op­por­tun­ity to amend the charges if in its view the cir­cum­stances out­lined in the in­dict­ment could con­sti­tute a dif­fer­ent of­fence but the in­dict­ment does not meet the stat­utory re­quire­ments.

² If fur­ther of­fences by the ac­cused come to light dur­ing the main pro­ceed­ings, the court may per­mit the pub­lic pro­sec­utor to add charges to the in­dict­ment.

³ Ad­di­tions are not per­mit­ted if the pro­ceed­ings would be made un­duly com­plex or this would af­fect the jur­is­dic­tion of the court or if a case in­volves co-of­fend­ing or par­ti­cip­a­tion. In these cases, the pub­lic pro­sec­utor shall com­mence pre­lim­in­ary pro­ceed­ings.

⁴ The court may only base its judg­ment on a charge that has been amended or ad­ded to if the party rights of the ac­cused and the private claimant have been ob­served. If ne­ces­sary, it shall ad­journ the tri­al.
