Murchison MLC Ruth Forrest's motion for a select committee to be established will be debated this week by the Legislative Council.

The move was in response to Mr McKim tabling his Dying With Dignity Bill, which would make voluntary euthanasia legal for some terminally ill Tasmanians.

Mr McKim yesterday raised concerns that the inquiry would delay debate, and labelled it unnecessary as "the community's opinions are well known on the issue".

"It's time the MPs showed the moral courage to actually vote," he said.

`I've promised terminally ill Tasmanians that I'm going to bring the debate on this year and I won't let them down."

Terminally ill patient Robert Cordover agreed that the issue was neither complex nor contentious.

Mr Cordover suffers from motor neurone disease that has taken away his ability to speak and is slowly taking away his ability to write.

"Under the current law I can have a messy suicide, not a peaceful death," he said.

"If have the right to live as I please within the law, then I ought to have a right to die as I please within the law."

His wife, Nika, read out his statements yesterday and emphasised that she, along with their children, had accepted his wishes.

"None of us want him to die but when he wants to die he should be allowed to," she said.

But Ms Forrest maintained that a committee inquiry was the next appropriate step.

"As legislators we have an important obligation to ensure any laws we pass are in best interests of Tasmania," she said.

"I do believe that there are many members of Parliament who have not fully considered all these matters in recent times as Mr McKim has had the time to do."

She envisaged the committee would call for submissions and take evidence in a tight time-frame.

"Most people would be able to do that in a short time-frame and it wouldn't disrupt Mr McKim's bill being debated," Ms Forrest said.
