repeal by implication

There are two well-settled categories of repeals by implication: (1) Where provisions in the two acts are in irreconcilable conflict, the later act to the extent of the conflict constitutes an implied repeal of the earlier one; and (2) if the later act covers the whole subject of the earlier one and is clearly intended as a substitute, it will operate similarly as a repeal of the earlier act. But, in either case, the intention of the legislature to repeal must be clear and manifest; otherwise, at least as a general thing, the later act is to be construed as a continuation of, and not a substitute for, the first act and will continue to speak, so far as the two acts are the same, from the time of the first enactment.
