Regulation 6 Right of the relevant UK authorities to interveneI1

In any proceedings to which regulation 3 applies, the relevant UK authorities are each entitled, on giving notice of their intention to be joined in accordance with paragraphs (2) to (4), to be joined as a party to the proceedings.

Notice may be given at any time during the proceedings.

Unless the court or tribunal orders otherwise, the notice must be given in writing to the court and to all the parties.

Where a Minister of the Crown has nominated a person to be joined as a party, the notice must be accompanied by the nomination in writing, signed on behalf of the Minister.
