Housing Association land parking problems

[dslcabrio]

Hi I wonder if anyone can help me with my problem. I live on a new housing development where the estate and roads are owned and maintained by the housing association through a service charge paid by residents. The roads are unadopted and my vehicle was parked in my designated parking space which is a linear parking bay that lies between the road and the footpath. I SORN'd my vehicle in Nov 2011 and it was insured but the MOT had run out. The vehicle was awaiting repair and was not being used. In January 2012 my vehicle was towed away by the local Environmental Health Officer watched by a police officer citing VERA as the reason. The EHO said that although the road was unadopted it was public highway because the public had access to it and therefore all vehicles had to be taxed, insured and MOT'd even if parked in designated bays and that SORN vehicles could not park anywhere on the estate. I reluctantly accepted this and paid the fine and towing fee etc and got my car back. Recently I parked my car on the road opposite a junction and received a trespass notice from the landlord stating that if i did not move the car which was in their opinion causing an obstruction it would be towed away under TORT at my expense. Surely my landlord cannot have it both ways and do I have a claim against my car being towed when SORN as in the initial problem.
