A man was arrested for interrupting State Parliament during the passage of legislation which recognises Aboriginal people in the South Australian Constitution.
The man was in the visitors gallery in the Upper House and called out that Indigenous people had not endorsed the legislation.
Parliament was suspended while the man was ejected and then arrested by police.
The bill passed the Legislative Council a short time later.
It recognises past injustices and acknowledges Indigenous South Australians as the traditional owners of the land.
Kaurna elder Jeffrey Newchurch says formal recognition of Aborigines in the state's Constitution is an important step forward for his people.
Mr Newchurch, who is from Point Pearce Aboriginal community on Yorke Peninsula, says it will help Aboriginal people work together with the Government.
"To at least put Aboriginal people on an equal footing and set up some kind of future for Aboriginal younger generations," he said.
"Now that we're recognised at least puts a little sparkle in your eye and gives you that energy to actually work with the Government and the wider community.
"We've all got a future in this state."
A referendum to recognise Aboriginal people in the Australian Constitution will be held at the next Federal Election.
Premier Jay Weatherill says the passage of the state bill will help the national campaign.
"All of these things add to a growing movement for change, a change about recognising the injustices of the past but importantly committing ourselves to a bright future for Aboriginal and non-Aboriginal Australians walking together in harmony," he said.
