full_context: Document 1: Parliament Act 1911: The Parliament Act 1911 is an Act of the Parliament of the United Kingdom. It is constitutionally important and partly governs the relationship between the House of Commons and the House of Lords which make up the two Houses of Parliament. This Act and the Parliament Act 1949 are technically to be construed as complementary in their effects. The two Acts may be cited together as the Parliament Acts 1911 and 1949.
Document 2: Parliament of the United Kingdom: The Parliament of the United Kingdom, commonly known as the UK Parliament or British Parliament, is the supreme legislative body in the United Kingdom, British Crown dependencies and British overseas territories. It alone possesses legislative supremacy and thereby ultimate power over all other political bodies in the UK and its territories. Its head is the Sovereign of the United Kingdom (currently Queen Elizabeth II) and its seat is the Palace of Westminster in the City of Westminster, one of the boroughs of the British capital, London.
Document 3: Great Offices of State: The Great Offices of State in the United Kingdom are the four most senior and prestigious posts in the British government. They are the Prime Minister, Chancellor of the Exchequer, Foreign Secretary and Home Secretary.

Document 4: Sovereign immunity in the United States: In United States law, the federal government as well as state and tribal governments generally enjoy sovereign immunity from lawsuits, although in some cases this immunity has been waived by law. Local governments in most jurisdictions enjoy immunity from some forms of suit, particularly in tort. The Foreign Sovereign Immunities Act provides foreign governments, including state-owned companies, with a related form of immunity—state immunity—that shields them from lawsuits except in relation to certain actions relating to commercial activity in the United States. The principle of sovereign immunity in US law was inherited from the English common law legal maxim "rex non potest peccare", meaning "the king can do no wrong."

Document 6: Human rights in the United Kingdom: Human rights in the United Kingdom are set out in common law, with its strongest roots being in the Bill of Rights 1689, as well as legislation of European institutions: the EU and the European Court of Human Rights.

In recent years, however, British human rights legislation has been criticised by some for what they perceive as excessive attention to the human rights of offenders at the expense of those of victims; high-profile cases, such as those of Learco Chindamo and the 2006 Afghan hijackers, have attracted controversy, sparking calls for the review of the Human Rights Act 1998 and other legislation. David Cameron in his second ministry announced plans to replace the Human rights Act with a "British Bill of Rights".

Document 12: Parliamentary privilege in the United Kingdom: Parliamentary privilege in the United Kingdom is a legal immunity enjoyed by Members of the House of Commons and House of Lords designed to ensure that Parliamentarians are able to carry out their duties free from interference. The privileges are freedom of speech, freedom from arrest on civil matters, freedom of access to the sovereign and that 'the most favourable construction should be placed on all the Houses's proceedings'. Parliamentary privilege is however something that forms part of the law rather than putting Members of Parliament above the law. The doctrine of Parliamentary privilege was unsuccessfully used to try and prevent details of 2010 MPs expenses scandal from emerging. In recent years the doctrine of Parliamentary privilege has made headlines in relation to the arrest of Damian Green and several cases relating to super-injunctions such as "RJW & SJW v The Guardian newspaper & Person or Persons Unknown" ('Trafigura') and "CTB v News Group Newspapers" leading to calls to reform the law relating to privilege.
