A joint statement has been issued this morning on behalf of the applicants in a legal challenge to the Northern Ireland protocol.
The hearing is due to take place in the Belfast High Court, being heard by Mr Justice Colton.
The Northern Ireland Unionists involves are Ben Habib, Baroness Hoey, Lord Trimble, Rt Hon Arlene Foster MLA, Dr Steve Aiken OBE MLA and Jim Allister QC MLA.
The statement reads: “Today we are looking forward to the commencement of our legal challenge to the EU Protocol.
“It is not just trade and economic prosperity but the constitutional integrity of the United Kingdom that requires defeat of the Union-dismantling Protocol.
“The purpose of this Judicial Review challenge is to undo the great wrong which was done in the imposition, without consent, of arrangements which leave Northern Ireland as a rule taker of foreign laws – over which we have no control, the United Kingdom partitioned down the Irish Sea and trade fettered disastrously with our biggest market.
“All this we believe under the Acts of Union and the assurances of the Belfast Agreement, as well as our basic democratic entitlement to be governed only by laws made by those we elect.
“We are grateful to our legal team under the leadership of John Larkin QC who have marshalled compelling arguments which we look forward to being expounded over the next few days.
“We also wish to acknowledge and thank all who have generously contributed financially to advancing this vital case. We may be the named applicants but we take this action on behalf of all who care about democracy, our economy, the future of the United Kingdom and basic fairness.”
