Section 468.   Sentence on offender already sentenced for another offence

(1) When a person already undergoing a sentence of imprisonment is sentenced
on a subsequent conviction to imprisonment or imprisonment for life, such imprisonment or
imprisonment for life shall commence at the expiration of the imprisonment to which he has
been previously sentenced, unless the Court directs that the subsequent sentence shall
run concurrently with such previous sentence:
Provided that where a person who has been sentenced to imprisonment by an order
under section 141 in default of furnishing security is, whilst undergoing such sentence,
sentenced to imprisonment for an offence committed prior to the making of such order, the
latter sentence shall commence immediately.
(2) When a person already undergoing a sentence of imprisonment for life is sentenced
on a subsequent conviction to imprisonment for a term or imprisonment for life, the
subsequent sentence shall run concurrently with such previous sentence.
