Thank you all for helpful feedback. I may now write in the past tense as the jalopy this morning has thankfully disappeared. I have been paying parking fees elsewhere for the past fortnight.
The car was parked on my parking space, ie: the parking space on my title of ownership. So it was not parked on common property – I can see how any remedy might differ as between abandoned on common parts and abandoned on an owner's private space.
From this helpful feedback I now see that an owner has no enforceable right where a car 'squats' on an owner's private space within a common property car park. There is no practical remedy that arises even if to all intents and purposes the law is on the side of the owner.
So I would think that an owners' corporation could hardly object to owners installing collapsible bollards in light of the above.
Thank you.
