Private goods on common property

I’m a position holder on our executive committee for my small block and have a disruptive owner.

Is it permitted for EC or their representatives to remove their property from a common area after we’ve asked them to move it? Storage of any item in common area is not permitted as part of the standard by-laws for this building.

And, if I wish to move to issuing notices of non compliance can I claim for legal/administration costs above the amount of the non compliance notice?
