It seems that you are being terminated because you say you have 'resubmitted' your app for review without actual changes to your app binary as you write
I revised all screenshots, removed disturbing imagery, added server-side content filters and a user-report function, and resubmitted with an explanation.
Apple, Inc. is a private company that lays down their own guidelines. So the court probably has no jurisdication whether or not there has been a due process. Furthermore, Apple, Inc. doesn't even promiss you a due promise if you read the Agreement that you have accepted.
Personally, I have zero or little respect for their review process because they use their spam bot to harass and intimidate membership-paying customers. I loved this company in the last 80s and 90s, though.
