Minn. Stat. § 645.39: IMPLIED REPEAL BY LATER LAW.

When a law purports to be a revision of all laws upon a particular subject, or sets up a general or exclusive system covering the entire subject matter of a former law and is intended as a substitute for such former law, such law shall be construed to repeal all former laws upon the same subject. When a general law purports to establish a uniform and mandatory system covering a class of subjects, such law shall be construed to repeal preexisting local or special laws on the same class of subjects. In all other cases, a later law shall not be construed to repeal an earlier law unless the two laws are irreconcilable.
