Hi Contractor,
You must be new in town - usually its the 4WD boyos [and gurlies] who are the worst for parking illegally on paths, verges, bus stops, etc.
Your posts appear contradictory:
#4 "It's astonishing to think management company rules supercede the law"
#5 "We do not have any rules governing parking."
Which is it?
Regardless of the above apparent confusuon, the estate is covered by several regulations, including planning, building and fire regulations.
The Planning Permission will specify places for parking to avoid congestion and reduce amenity - there are no other "legal" places to park in the estate in terms of the permission except roadways and parking spaces.
The building control regulations may speficy distances between buildings to prevent spread of flame - its possible that unauthorised parking will increase the risk.
The Fire Services Act may require access to be kept clear for emergency vehicles.
The estate as a whole may be defined as a working area for those people engaged in sweeping, gardening, cleaning and maintenance.
It may be that improper parking may place such persons at risk during their working hours - its a long shot but H&S may play a part.
HTH
