1 The criminal justice authorities are obliged to commence and conduct proceedings that fall within their jurisdiction where they are aware of or have grounds for suspecting that an offence has been committed.
2 The cantons may provide:
a.
for the exclusion or limitation of criminal liability for statements made in the cantonal parliament by the members of their legislative and judicial authorities and of their governments;
b.
that the prosecution of members of their authorities responsible for the execution of sentences and measures and judicial authorities for felonies or misdemeanours committed while in office be made subject to the authorisation of a non-judicial authority.
