Section 31 of the Code of Criminal Procedure states that a court, subject to Section 71 of the IPC, is competent to try multiple offences during a trial in a single case and can order jail terms as punishment after conviction, which could run either concurrently or consecutively, depending upon the gravity of the offences.
In the case of concurrent sentences, a court orders multiple jail terms for a convicted person and these terms run at the same time. In consecutive sentences, the jail terms run one after the other.
Courts are empowered to inflict a maximum punishment of 14 years or twice the amount of punishment which it can order for a single offence, whichever is lower.
