s168 - Registers to be maintained: companies must set up and maintain certain registers (eg members).
s175 - Correction of registers: To correct a company register, application should be made to the Court.
s176 - Evidentiary value of registers: In the absence of
evidence to the contrary, a register kept under this Chapter is proof of the matters shown in the register.
Combining these three, what's shown in the company registers is taken as correct unless you can show evidence to prove they are incorrect. The only way to force their correct is by court order.
