Erm, I think Dr. De Vos made quite clear that he is not willing to wager on any outcome just yet. There are two conflicting principles at stake here. There is the role of the court, the highest power in the land under our system, to as watchdog over government but there is the issue of seperation of power.

The last time there was a case where these issues so strongly conflicted was the TAC case back in 2006. In that case the then court eventually found that the department of health's failure to make anti-retroviral treatments such as Nevirapine available in state hospitals was a failure to live up to it's constitution obligations to provide adequate healthcare to all South Africans.
It then ordered the department to do so. At the time this was quite a big issue - even though most scholars and voters agreed with the TAC it raised a serious seperation of powers debate as what the court ordered was tantamount to prescribing a specific policy. 

What will happen this time is anyones guess
