Tongue in cheek understood and appreciated. As to who wants to limit what constitute a wetland - well, who else?
In all seriousness, the case gives SCOTUS an opportunity to revisit its earlier decision in Rapanos v US (2006) which, without going into exhaustive detail, iterated the “significant nexus” test for determining whether wetlands could be “navigable waters” for jurisdictional purposes. In a sense, the decision went 4-1-4 (what constitutes the “plurality” opinion was of Scalia’s authorship and included a stab at the Corps of Engineers as exercising the discretion of “an enlightened despot”), and the “1” was authored by Justice Kennedy, also no longer on the bench. So, sixteen years later, it’s a different court; that four Justices agreed to grant cert doesn’t bode well.
