This part is really interesting:

If Texas foregoes seeking a preliminary injunction – or files and is appropriately denied that interim relief –then any court order affecting Trump’s ability to continue DACA could only come after the court reaches a final judgment. Before the court could reach a final decision, it would have to allow discovery – evidence gathering – and depositions – witness questioning – and it would have to resolve critical factual disputes. Many of these disputes could center on standing and whether Texas has any injury traceable to DACA, or whether the benefits of DACA to the state outweigh the costs. Whatever the issues, getting to a final decision would not be quick. In all likelihood, a final decision would not come until well into 2018, even toward the end of 2018.
