perhaps the judge picked a poor example, but nonetheless, the only route left to the president is rule making and executive orders. and with a split congress, nothing will get thru the senate, thus, congress cannot undo whatever they may object to.
i won't put it past this president to assemble some clever people and find something in the law that gives him an opening. he did it with work for welfare, and that was against the way the law was written. he will make rules and issue orders and let those who oppose take the action to court, where it will take years to reach a decision about whether the president exceeded his authority or not. meanwhile, the rule or order will stand and we all will get to have it apply to our lives.
