The Constitution limits the political rights of Pakistan's non-Muslims. Only Muslims are allowed to become the President or the Prime Minister. Only Muslims are allowed to serve as judges in the Federal Shariat Court, which has the power to strike down any law deemed un-islamic, though its judgments can be overruled by the Supreme Court of Pakistan. However, non-Muslims have served as judges in the High Courts and Supreme Court. In 2019, Naveed Amir, a Christian member of National assembly moved a bill to amend the article 41 and 91 of the Constitution which would allow non-Muslims to become Prime Minister and President of Pakistan. However Pakistan’s parliament blocked the bill.
