The above provision is clear and unambiguous. The section deals with endorsement of a warrant of commitment to prison and computation of a term of imprisonment. It does not stipulate that a term of sentence cannot commence from the date the Courts verdict is pronounced. In any case, since the appellant was sentenced to imprisonment for life, the issue of computation of term or time of imprisonment does not arise in this case.

It is a duty imposed by law. In page 561 of the said case, His Lordship, Fabiyi, JSC, held as follows: The appellants counsel should be reminded of the doctrine of separation of powers as enshrined in the 1999 Constitution. The legislature is to enact laws while it is the duty of the judiciary to interpret the
