The assembly was called to propose a universal land tax in which the higher classes would no longer be exempt from.
A friend of mine wrote the sentence above. He believes it is grammatically correct. (We both agree that the "which" in the sentence refers to that universal tax.)
Since the phrase "exempt from in which" does not make sense because of the two consecutive prepositions, "from " and "in", I believe the sentence is grammatically incorrect. In fact, I went on further to say since it was such an obvious basic mistake and that he could not readily agree with me after I explained why it is incorrect, his English grammar must be pretty bad, although his English is much better mine otherwise.

Is the usage of "in which ... be exempt from" in the sentence correct? What about those online grammar checkers?
