I want to know the answer to the following question:
Which entities have the capability to refer a bill to the Supreme Court?
All the background I'm provided with is that "After a bill has been passed, the Presiding Officer of the Scottish Parliament submits it to the monarch for royal assent after a four-week period, during which the Advocate General for Scotland, the Lord Advocate, the Attorney General or the Secretary of State for Scotland may refer the bill to the Supreme Court of the United Kingdom (prior to 1 October 2009, the Judicial Committee of the Privy Council) for review of its legality.". Is that enough to answer the question?
Answer: yes
