Notably, a statute does not disappear automatically merely because it has been found unconstitutional; it must be deleted by a subsequent statute. Many federal and state statutes have remained on the books for decades after they were ruled to be unconstitutional. However, under the principle of stare decisis, no sensible lower court will enforce an unconstitutional statute, and any court that does so will be reversed by the Supreme Court. Conversely, any court that refuses to enforce a constitutional statute (where such constitutionality has been expressly established in prior cases) will risk reversal by the Supreme Court.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What court created the principle of stare decisis?
Ah, so.. unanswerable

The Pyx Chamber formed the undercroft of the monks' dormitory. It dates to the late 11th century and was used as a monastic and royal treasury. The outer walls and circular piers are of 11th-century date, several of the capitals were enriched in the 12th century and the stone altar added in the 13th century. The term pyx refers to the boxwood chest in which coins were held and presented to a jury during the Trial of the Pyx, in which newly minted coins were presented to ensure they conformed to the required standards.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When does the Pyx Chamber date to?
Ah, so.. the late 11th century

Articles 41 and 68 of the constitution empower the sovereign to withhold royal assent from bills adopted by the Legislative Assembly. In 2010, the kingdom moved towards greater democracy, with King George Tupou V saying that he would be guided by his prime minister in the exercising of his powers. Nonetheless, this does not preclude an independent royal decision to exercise a right of veto. In November 2011, the assembly adopted an Arms and Ammunitions (Amendment) Bill, which reduced the possible criminal sentences for the illicit possession of firearms. The bill was adopted by ten votes to eight. Two members of the assembly had recently been charged with the illicit possession of firearms. The Prime Minister, Lord Tuʻivakanō, voted in favour of the amendment. Members of the opposition denounced the bill and asked the King to veto it, which he did in December.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What statement by King George Tupou emphasized democracy?
Ah, so..
he would be guided by his prime minister in the exercising of his powers
