Even in America, judges have to properly examine all the arguments and evidence presented to them and weigh those against what the law says before coming to a decision. It’s not like taking a decision about what color car to buy.
I personally don’t think it’s a good omen that Curtis Morrison started asking now (not months ago when he was collecting people for his case) for petitions to congress to extend the DV date. That sounded like desperation to me. I hope I’m wrong and that its a positive outcome, at least for those dv2020 who are far enough along in the process to be able to get visas by month end.
