He wants medical assistance to die when he has less than six months left to live, still has the mental capacity to make the decision and has made a "voluntary, clear, settled and informed" choice.
Mr Conway lost a Court of Appeal challenge in June against an earlier High Court rejection of his case that the "blanket ban" on assisted dying was an unjustified interference with his human rights.
He sought to challenge that at the Supreme Court and justices took the unusual step of considering his case at a hearing last week.
During that hearing, Mr Conway's lawyers told the court the retired lecturer does not accept that withdrawal of his "non-invasive ventilation" (NIV), which he needs 23 hours a day, would be an acceptable way for him to end his life.

In response to today's judgement, Mr Conway said:
