The Law Society says proposed laws to limit use of suspended sentences could threaten court independence.

The South Australian Government wants to lift the threshold for violent offenders and those with links to organised crime.

Legslation to be introduced next month would require exceptional circumstances to be proved before a suspended jail sentence could be imposed.

Law Society president John White is keen to see more detail of proposed changes.

"The Society understands the need to keep sentencing laws under review but we always have a concern about whether prescriptive laws interfere with the independence and discretion of the courts," he said.
