We add a flowchart to this post because the Washington Supreme Court on page 15 of its opinion in Yim v. City of Seattle, No. 95813 (Wash. Nov. 14, 2019) (em banc) (Yim I), includes a flowchart that purports to solve the regulatory takings puzzle once and for all.
Really.
You should check it out. We use “purports” because (surprise, surprise) the court gets it wrong. Flowcharts — also known as decision trees (if A, then B) — are supposed to help, not confuse. And this one doesn’t help if you are trying to figure out if a regulation effects a taking under the Fifth Amendment (and, as a result of the Yim I opinion, under the Washington Constitution).
If that were not bad enough, in a companion opinion in the same matter (on certified questions from the federal court), Yim v. City of Seattle, No.
