Mich. Comp. Laws § 8.3u: Re-enactments.

Sec. 3u.

The provisions of any law or statute which is re-enacted, amended or revised, so far as they are the same as those of prior laws, shall be construed as a continuation of such laws and not as new enactments. If any provision of a law is repealed and in substance re-enacted, a reference in any other law to the repealed provision shall be deemed a reference to the re-enacted provision.
