Knick v. Township of Scott involves a common theme before the Supreme Court. One party is asking it to overturn long-standing Supreme Court precedent. Unfortunately for states and local governments the precedent on the chopping block arises in the property rights context (where the more conservative Supreme Court tends to favor property owners) and is generally considered favorable to states and local governments.
The Township of Scott adopted an ordinance requiring cemeteries, whether public or private, to be free and open and accessible to the public during the day. Code enforcement could enter any property to determine the “existence and location” of a cemetery.
The Constitution’s Takings Clause states that “private property [shall not] be taken for public use, without just compensation.” Rose Mary Knick sued the county in federal (rather than state) court claiming the ordinance was invalid per the Takings Clause after code enforcement went onto her property without a warrant looking for a cemetery.
