Divorce by cell phone

A court in Dubai has validated the divorce of a couple after the man sent his wife a text message on a mobile phone telling her they were divorced. The text of the message actually read: "Why are you late? You are divorced." Apparently, that's all you need to make it official in Dubai (if you're male, that is). The couple is actually still together, so I'm not sure why the case went through, but I get the feeling that I don't really understand the legal system in Dubai.
