What is the word or expression for when someone acts as though something is on the up and up, even though they know they are exploiting or abusing a system for their own benefit. For example, imagine there is an "activist" judge who uses a jaded interpretation of the law to rule against a large corporation he doesn't like, and we have the sentence:
Judge Clancy's cynical and self-serving interpretation of the Wildlife Act threatens to put our company out of business.
Here I have used the word "cynical" but that is not exactly right. We have sort of the idea of crocodile tears where someone pretends to be normal, but has a hidden agenda.
I think the right word may be "disengenuous", but am not sure.
