In this case private property rights were being violated. If it was not upheld, in future SAPS and government would have stood back in similar cases and make individuals and private citizens bear the burden of their failure to protect each citizen's rights and the consequences of their bad policies. In the circumstances the judgement was correct. SAPS as an agent of state failed, if that was the evidence presented, and government, of which the city is part, must accept that. So I don't agree the judge was wrong. 
If your property was invaded and rendered useless and valueless, would you say the same? The current policy, as I noted, is at fault - it's creating huge problems and must be changed but politically, the ANC won't, as in so many other areas.
