The wording of the Criminal Justice Act does not mention locking and so the definition of ``folding pocket knife'' was settled through case law. In the Crown Court appeal of Harris v. DPP (1992) and the Court of Appeal case of R. v Deegan (1998) the ruling that 'folding' was intended to mean 'non-locking' was upheld. As the only higher court in England and Wales to the Court of Appeal is the Supreme Court, the only way the decision in R. v. Deegan could be overturned is by a dissenting ruling by the Supreme Court or by Act of Parliament.

Minnesota adopted the English Language Arts standards but not the Mathematics standards. Although starting as a fast trend, the curriculum lost momentum and found at least 12 states introducing legislation to prohibit implementation. Three states that initially adopted Common Core have since decided to repeal or replace it: Indiana, Oklahoma, and South Carolina.
