Not like Quangos - Statutory Boards at least in Singapore are a part of a ministry, but they are given full autonomy [0] to recruit, administer, and manage within their remit as legislated.
Quangos are a half assed attempted at doing something similar while trying to include some "inclusion", but with none of the checks and balances.
The reality is, not every Tom, Dick, and Harry should have a say on water management or R&D prioritization.
