NO AUTHORITY, MEH?

Even if you're a Minister of Education or for that matter the Deputy Prime of
Malaysia, you have no power or jurisdiction over school heads on disciplinary
matters? Well this seemed to be so according to this man

who happens to be our Deputy Prime Minister of Malaysia Muhyiddin Yassin
also the Education Minister.He said his ministry had no jurisdiction
on disciplinary matters involving "senior government officials
above the pay grade 48".
He said since the school heads possessed grades "that are quite
high", only the Public Service Department (PSD) could act
against them.
Huh, it makes me asking whether the PSD has more authority than the
Education Minister? If that is the case, then can someone tell me WTF
does the Education Minister do?
DAMMIT!Playing marbles in the ministry corridors?
