The Tasmanian Government has been accused of using the "highly unusual" tactic of introducing legislation directly into the Upper House instead of going to the Lower House first.

Four bills were introduced to the Upper House this week when there was no other business, prompting outrage from both Labor and the Greens.

They included amendments to the Motor Accidents Liabilities and Compensation Act and the Health Practitioners Tribunal Act.

Long-serving Labor MP David Llewellyn said it was highly unusual that the Lower House did not get to debate the legislation first as normal.

"In the 26 years that I've been in this chamber you could count on one hand the number of bills that come down from the legislative council," he said.

"This is the house of the people, and this is where the legislation is initiated and the other place [the Upper House] is the house of review."

Greens MP Cassy O'Connor agreed the practice was unusual.

"Is it because they haven't got enough work upstairs because the legislation program here is so scant or is it because they want an easier ride with their legislation?" she asked.

Health Minister Michael Ferguson did not see a problem.

"One of the bills is, in fact, a bill from an independent member," he said.

"The two houses are equal - members of Parliament in either house are entitled to bring in legislation.

"I don't see why you're so offended by the concept of that, the Attorney-General might actually bring in a bill."

It comes after the Upper House considered taking an extended break earlier in the year because of the light legislative workload.

Practice is not unusual: Attorney-General

Windemere MLC Ivan Dean said it was the first time he had seen the usual process reversed.

"I've certainly seen private members bills come through our place but this is the introduction of a bill of course, by a minister and that's absolutely unusual," he said.

"I don't think it's ever happened since I've been there [and] I've been there for 13 years.

"How long before that happened [last time], maybe it was before the turn of the century.

"So I would think it was probably that long ago at least, and probably longer."

But Leader of the House, Vanessa Goodwin, said the practice was not out of the ordinary.

"It's not unusual for bills to be introduced in the legislative council by the responsible minister," she said.

"It's the first time I've done it but certainly it occurred under the previous government.

"On this particular occasion they were four justice bills, all relatively non-controversial, and it was decided that they would be tabled and dealt with in the Upper House first.

"It was a fairly straight forward thing for that to occur."

Dr Goodwin said it was a way of bringing legislation into the house during what had otherwise been a quiet week for MLCs.

"Certainly it helps us manage our legislative program if I can, as a responsible minister, table bills in the Upper House," she said.

"I think that was probably the rationale in previous governments.

"I checked with all my legislative council colleagues that they were OK with that."

A Government media spokesman released a statement which said there were a number of recent examples of bills being tabled in the Upper House, contrary to Mr Dean and Mr Llewellyn's comments.

He said they included bills tabled in 2008 and 2009 by former Labor treasurer Michael Aird, when he was leader of the government in the Upper House.
