In Pace v Edel-Harrelson, 499 Mich 1; 878 NW2d 784 (2016) the Michigan Supreme Court ruled that "the plain language of MCL 15.362 [of the WPA] envisions an act or conduct that has actually occurred or is ongoing," and, therefore, "MCL 15.362 contains no language encompassing future, planned, or anticipated acts amounting to a violation or a suspected violation of a law."
This decision overrules the Michigan Court of Appeals' earlier and differing interpretation of MCL 15.362 in the same matter, Pace v Edel-Harrelson, 309 Mich App 256; 870 NW2d 745 (2015), and a factual background of this case as well as the Court of Appeals' now-reversed decision can be found here.
