Lecretia Seales, a lawyer who has terminal brain cancer, is asking the High Court at Wellington for a declaratory judgment that would protect her GP from prosecution if, and when, her doctor assists her to die.
Ms Seales argues she has a right not to be subjected to cruel, degrading or disproportionately severe treatment under the Bill of Rights Act.
The Care Alliance, the Voluntary Euthanasia Society and the Human Rights Commission sought approval from the High Court on Tuesday to participate in the hearing on May 25.
In a decision yesterday, Justice David Collins said he would allow it with stringent conditions to prevent delays, because it may assist him to make a decision.
