Convicted criminals who have served their sentences in Guernsey will now be protected by law from being discriminated against.
The States has passed a rehabilitation of offenders law which means islanders with minor offences will not have to declare them after a certain period.
It does not relate to anyone serving a prison sentence of more than 30 months.
But a politician has questioned some practical aspects of how the legislation will work.
St Peter Port deputy John Gollop said: "How easy it will be to detect whether a candidate is turned down for a job because of a concern like that will be hard to know.
"And I'm wondering if, in the normal course of events, people in the recruitment field would still be able to legally ask these questions and expect a totally comprehensive answer."
