As expected, 31 Jan 2020 saw the following
With reference to depositary notification Choice of Court No. 01/2019, dated 2 January 2019, regarding the accession to the Convention by the United Kingdom, and with reference to depositary notifications Choice of Court No. 03/2019, dated 29 March 2019, Choice of Court No. 04/2019, dated 12 April 2019, and Choice of Court No. 07/2019, dated 31 October 2019, regarding the suspended accession of the United Kingdom to the Convention, the depositary communicates that the Instrument of Accession, Note Verbale and Declarations were withdrawn by the United Kingdom on 31 January 2020.
In the meantime the UK keeps riding along in the Convention due to the EU’s accession.
Don’t worry, another UK accession will probably be along later in the year as the UK approaches ‘third party state’ day (TPS day) on 31 December 2020 – possibly to be followed by another ‘withdrawal’ in the event that the UK and the EU conclude an agreement on judgments and jurisdiction before the end of the implementation period.
