Environmental Planning and Assessment Act 1979

Judicial notice is to be taken of a contributions plan and of the date on which the plan came into effect.

It is to be presumed, in the absence of evidence to the contrary, that all conditions and preliminary steps precedent to the making of a contributions plan have been complied with and performed.

The validity of any procedure required to be followed in making or approving a contributions plan is not to be questioned in any legal proceedings except those commenced in the Court by any person within 3 months after the date on which the plan came into effect.

The amendment or repeal, whether in whole or in part, of a contributions plan does not affect the previous operation of the plan or anything duly done under the plan.
