    Commons Briefing Papers

    14.11.2016Brexit and the EU Court
    The High Court has appealed to the Supreme Court for a decision on whether the Government can start the Brexit process by triggering Article 50 TEU using Prerogative powers. Some press reports said the Court of Justice of the EU (CJEU) would have the last word on this. But can the CJEU rule on matters of UK constitutional Law? Many experts believe that the question central to the case, but not ruled on by the High Court, was whether Article 50 can be withdrawn. If it can be revoked, then the argument that Article 50 notice leads inevitably to a loss of rights under the European Communities Act 1972 might not hold. This paper looks at the questions of revocability and referral to the EU Court.

    18.07.2016Citizens' Assemblies and Constitutional Conventions

It also sets out details of the wide-ranging Irish Constitutional Convention established in 2012, and the 2011 Icelandic National Forum and Constitutional Assembly which produced a new draft constitution.

The issues include the method of leaving the EU, continuing parliamentary scrutiny of EU business and the withdrawal negotiations, and the implications of Brexit for Scotland and Gibraltar.
    30.06.2016Brexit: how does the Article 50 process work?
    This Commons Library briefing paper looks at the process of withdrawing from the EU under Article 50 of the Treaty on European Union. There could be a complex and difficult negotiation lasting two years or more, or the UK could leave without settling its exit terms or its future relationship with the EU.
    13.06.2016Wales Bill 2016-17
    Briefing paper for the second reading of the Wales Bill 2016-17.
    Impeachment was a means by which Parliament could prosecute and try individuals, normally holders of public office, for high treason or other crimes and misdemeanours. Impeachment is considered obsolete, as it has been superseded by other forms of accountability, and the rules underpinning the procedure have not been adapted to modern standards of democracy or procedural fairness
    18.05.2016A British Bill of Rights?
    The Conservative Party went into the 2015 General Election with a manifesto commitment to 'scrap the Human Rights Act and curtail the role of the European Court of Human Rights.' This note provides a brief introduction to the Human Rights Act 1998; the European Convention on Human Rights and the work of the European Court of Human Rights.

It does this through addressing a selection of the ceremonial and formal roles of the Sovereign: the State Opening of Parliament and its prorogation and dissolution; the calling of a new Parliament, in light of the Fixed-term Parliament Act 2011; Royal Commissions and royal assent; and Queen's consent. The briefing also addresses a number of aspects of the Sovereign's communications and relationship with Parliament more broadly, through Addresses and messages and the Palace of Westminster itself. It provides facts and figures relating to Queen Elizabeth II including: the number of Acts that have received Royal Assent during her reign, Addresses given by the Queen to both Houses in Westminster Hall, and the wording of Queen Elizabeth II's first message to Parliament on her accession to the throne in 1952.
