Since February 1st, 2020, the UK is no longer a member of the European Union (EU). On the same day, the negotiated Withdrawal Agreement (WA) entered into force. It contains a complex transitional regime involving the continued application of large parts of EU law to and in the UK during a short transition period. Yet, some provisions of the WA alter the application of EU law to and in the UK and/or introduce new legal rights and obligations regarding, inter alia, civil rights and dispute settlement. Whether and how the long-term EU-UK relations will be regulated cannot yet be foreseen and various options are available - the WA could still yield a no-deal Brexit or an ambitious free trade agreement. It may as well lead into an impasse as it might become a pathway to new, solid relations between the EU and the UK.
