Britannian korkein oikeus päätti tänään, että EU:sta eroamiseen (ns. Brexit) tarvitaan parlamentin päätös, eikä hallitus voi omalla päätöksellään käynnistää neuvotteluita.

Supreme Courtin lehdistötiedotteesta:

The Supreme Court considers that the terms of the ECA, which gave effect to the UK’s membership of the EU, are inconsistent with the exercise by ministers of any power to withdraw from the EU Treaties without authorisation by a prior Act of Parliament

  • Section 2 of the ECA authorises a dynamic process by which EU law becomes a source of UK law and takes precedence over all domestic sources of UK law, including statutes [60]. So long as the ECA remains in force its effect is to constitute EU law as an independent and overriding source of domestic law [65]. It operates as a partial transfer of law-making powers, an assignment of legislative competences, by Parliament to EU institutions, unless and until Parliament decides otherwise [67-68].
  • It is common ground that UK domestic law will change as a result of the UK ceasing to be party to the EU treaties and the rights enjoyed by UK residents granted through EU law will be affected [69].
  • The Government argues that the 1972 Act does not exclude the power for ministers to withdraw from the EU Treaties, and that section 2 of the Act actually caters for the exercise of such a power as it gives effect to EU law only so long as the power of withdrawal is not exercised [75]. However, there is a vital difference between variations in UK law resulting from changes in EU law, and variations in UK law resulting from withdrawal from the EU Treaties. Withdrawal makes a fundamental change to the UK’s constitutional arrangements, by cutting off the source of EU law, [78-80]. Such a fundamental change will be the inevitable effect of a Notice being served [81]. The UK constitution requires such changes to be effected by Parliamentary legislation [82].
  • The fact that withdrawal from the EU would remove some existing domestic rights of UK residents also renders it impermissible for the Government to withdraw from the EU Treaties without prior Parliamentary authority [83].
  • It would have been open to Parliament when enacting the ECA to authorise ministers to withdraw from the EU Treaties, but clear words would have been required; not only are there no such clear words, but the provisions of the ECA indicate that ministers do not have such power [87, 88]. Withdrawal is not authorised by section 2, which envisages ministers taking part in the EU law-making processes: withdrawing from the EU is doing the opposite [95].
  • The fact that ministers are accountable to Parliament for their actions is no answer constitutionally, if the power to act does not exist in the first place and where (as the court has been asked to assume) the exercise of the power would be irrevocable and pre-empt any Parliamentary action [92].
