>including the hundreds of thousands of law-abiding citizens on the housing waiting list.
In engineering we have a term 'root cause analysis' - describing the process by which, when a problem occurs, we don't actually look at the problem itself that much - we do an investigation to determine the underlying (root) causes that led to the problem - and fix THOSE - which not only resolves the problem but also prevents it reoccurring.
In this case - you've actually done it already, and overlooked it a bit - it's right there in that line. The lists are hundreds of thousands long? No wonder people jump the queue - is anybody surprised that, among hundreds of thousands there are tens of thousands who are gatvol of waiting ?
All other aspects aside -the court ruled correctly, in line with what the constitution says-  whether you like it or not, whether you agree with it or not. You don't get to ask if it's sustainable. You were elected to MAKE it sustainable. That's literally your job.
