The Supreme Court has set a provisional date of 19 February to hear an appeal by Marie Fleming, who last week lost her landmark challenge to the ban on assisted suicide.
Ms Fleming, 59, who has multiple sclerosis, is seeking help to end her own life.
She sought to have the law on assisted suicide declared invalid under the Constitution and incompatible with the European Convention on Human Rights.
A three-judge divisional High Court ruled against her, saying any relaxation of the ban would adversely affect wider society as it would be open to abuse.
The case has been fast-tracked due to Ms Fleming's medical condition.
Seven judges of the Supreme Court are expected to hear the case as it concerns Constitutional issues.
Ms Fleming was awarded the costs of her High Court case despite losing it because the issues raised were deemed to be of exceptional public importance.
