If the person is a CURRENT public servant who holds contributions in a pension account that relate to the person’s past employment in the private sector, then the person IS able to withdraw as long as the funds were NOT contributed by a public sector entity (i.e.: a statutory authority or a Government-owned company.)
If the person was previously employed with the public sector and has now left that employment (i.e.: working in the private sector or unemployed), then any contributions, regardless if the person was paid by a public sector entity, can be accessed.
