EC in breach of by law?

Our Strata Plan has a Special By Law (Floor Coverings) in place which was approved by a 100 % vote of all owners at an AGM.

Broadly, the by law provides that an Owner of a lot must ensure that all floor space within the lot is covered or otherwise treated to an extent sufficient to prevent the transmission from the floor space of noise likely to disturb the peaceful enjoyment of the owner or occupier of another lot.

Any changes of existing floor coverings must be approved by the EC, and acoustic reports and specifications of materials used  need to be submitted.

Subsequent to the implementation of this by law, the EC has decided to impose a blanket veto cum ban on any future application for the installation of tiimber flooring.

My question is: Can an EC impose a ban of this nature, without giving due consideration to the individual proposal and details of materials used? There is a difference between high end timber such as parquetry and a low price range laminate, after all and one would think that on the basis of the governing by law each application needs to be considered on its own merits??
