Saudi Arabia and Dubai do not have Islamic law systems-they barely have legal systems at all. There is no method or referring to Islamic jurisprudence in these cases; there is simply what some judge says, and if you disagree, he might have you killed for trying to embarrass him or challenging his authority. The problem in these places is a complete lack of any law, not "islamic law".
The consensus view, from what I can gather, on this subject in Islamic law is that once a credible account is made out by the accuser, the burden shifts to the defendant to disprove the accuser's complaint. If the defendant cannot disprove the complaint, then he is subject to one of two penalties:
a lashing if he used deceit or mental pressure to complete the crime, or
death if the used a weapon or the threat of death to complete the crime, and there is physical evidence of some sort that cannot be denied.
The accusation that there is something like a basis in Islamic law for punishing the victim is complete garbage. There is no such rule, and any Muslim you ask about this will find it offensive in the extreme to suggest that he's religiously required to treat rapes so lightly.
