New laws in South Australia could see all but one of the state's existing laws suspended for tech companies in the name of research and development.

The Greens have accused the State Government of kowtowing to technology giants like Google and Tesla under the guise of attracting research dollars to South Australia.

"Criminal law, environmental law, animal welfare, child protection, I see no reason the Government could justify suspending child protection laws in the name of research and development," Greens MLC Tammy Franks said.

"I don't think it's worth giving a blank cheque for big corporations to do whatever they like, against the laws of our state, without the Government being upfront about which laws they propose to dis-apply and how it would work."

Read literally, the Research, Development and Innovation Bill 2017 would allow a minister to order, "to the extent that the Governor considers necessary for the purposes of the project or activity … provide that an act, specified provision of an act, or any other law does not apply", with the sole exception of Aboriginal heritage laws.

Attorney-General John Rau told the ABC it would not be a "free pass" for tech giants to bypass basic laws for research and development purposes.

He compared the measures to existing laws that allow certain road and transport rules to be suspended for the testing of driverless cars.

"A declaration can only be made if it is in the public interest and even then only for a limited time, and any declaration can be disallowed by either house of Parliament," he said.

But the Law Society of South Australia expressed concerns a government would have powers to declare a law does not apply.

"This could have unintended effects, such as providing foreign companies with potentially a much easier way to obtain exemptions under the Equal Opportunity Act," president Tony Rossi said in its submission.

"A better approach … is to identify the specific potential barriers and address such matters."

Ms Franks said she was also concerned about the fact Deputy Premier John Rau sent copies of the bill to Google, Amazon, Apple, Tesla, Microsoft, Samsung and Facebook.

"John Rau's gone off and written to Google, to Amazon, to Apple, to Tesla — what is it he has in mind?" she said.

"In the dying days of Parliament, we've got a bill that proposes every single law of the state can be suspended or dis-applied, except for Aboriginal heritage, in the event there's an approval given for one of these research and development plans.

"They need to come clean and tell us which laws it is they really want to suspend."

The laws have passed SA's Lower House and are among the bills the Government wishes to pass in the Upper House this week before Parliament rises until the next election.
