I was educating a friend as to the difference between these two words, and she told me that her lecturer used the word compliment in a way similar to comply. The sentence that I got from my friend was the following: "The most famous issue raised in the High Court was the case of Imbree v The Commonwealth in which the government circumvented compliment with the policy recommendations outlined in the Tony Fitzgerald Inquiry." That's the sentence I got from my friend. To me, regardless of the word compliment, the sentence doesn't make sense. So I asked her to elaborate on the actual issue. Apparently, it's something about the first case in challenging Government policy decisions - nowadays, in common law, you can't challenge Government decisions relating to policy. I don't know how well she understands this issue, though. In any case, I said that I believed her lecturer to be wrong and that compliment should be compliant. Any thoughts on this?
