I've had a few "well documented cases" shared with me in my time. Generally they are lengthy rants that make it clear that the author doesn't understand the constraints or goals of the business.

Occasionally, there will be some useful insights mixed in, but that is rare. I'd suggest rather than trying to make the case independently, find a trusted party, tell them that you have concerns about X, and let them drive the conversation. You may pique their interest, or give them a chance to validate concerns they already have.
