Agree with Anil. Having talked to many Bschool adcoms in our live chat sessions, I can say that most schools would not bar you from applying even if you already have an MBA degree as long as you provide them a
strong justification for a second MBA degree. Underlined part in previous sentence is extremely important. You will need to give them convincing answers for (1) What were the reasons/circumstances for getting 1st MBA degree, (2) What are your present career aspirations, (3) why current MBA degree is not sufficient for fulfilling your present career aspirations, and finally (4) how the school you are now applying to will help you attain your post MBA goals. You will have to do a lot of introspection to find out proper answers to all these questions.
