(1) If the conditions for more than one measure are fulfilled but the intended purpose can be achieved through individual orders from among their number, only those individual measures shall be ordered. Priority among a number of suitable measures shall be given to those which pose the least burden on the offender.

(2) In all other cases, measures shall be ordered concurrently unless the law provides otherwise.

(3) If more than one custodial measure is imposed the court shall determine the sequence of their enforcement. Before any measure has been fully served the court shall order the enforcement of the next if its purpose still requires detention. Section 67c(2) 4th and 5th sentences shall apply mutatis mutandis.
