You are an HR professional, and your question pertains to proof of clearance of the probation period. Your query is related to the probation period governed by the Probation of Offenders Act, rather than any of the HR (Labour) Acts. This forum focuses solely on the probation period in the context of service or employment.
As I have a background in Law, I can provide an answer.
Understanding the Probation of Offenders Act
The Probation of Offenders Act allows for the release of offenders following admonition or during a probation period, along with matters connected thereto. This release is contingent on good conduct, as an alternative to sentencing the offender to imprisonment. The court is empowered to release offenders based on confidential reports submitted by Probation Officers and may also require the released offender to pay compensation and costs.
In my opinion, the court that granted you probation will issue a clearance certificate, not the police.
I acknowledge that my response is based on past studies, and I am not currently a practicing lawyer, so I may not be aware of the procedural specifics. Corrections or clarifications are welcome.
