The contract can or has been amended to drop the cma requirement. Nobody really knows the answer except for ABK and MS. MS either closes or extends if the pi isn't granted. We will know the answer very soon(24 hours)
1 country destroying a merger when the rest of the world said it's fine is a bad predecent. Comity is a thing for a reason.
I don't know any major merger where the CMA blocked it, and killed it, and the rest of world said okay. What's the case you're referring to?
We shall see very soon. July 18th is rapidly approaching and the judge makes her decision tomorrow.
