Retrospective exclusive use by-law – Garden changes

A good question for a Friday!

In our block of town houses, one owner decided to rip out a large portion of the landscaped common property garden and plant some vegetables.  A formal complaint was submitted and the strata managers told the OC to reinstate it to its previous state.  Everyone was too scared to point at the owner who did it, so the OC must pay for it.

Now they are talking about calling an EGM to grant that owner exclusive use, presumably so we don’t have to pay for it to be fixed.

Can the OC retrospectively grant an owner exclusive use?  Or does the area need to be reinstated first and then exclusive use granted?

Any advice would be much appreciated!
