1. Many believe up to 3-4 million people would have qualified for this relief (which is only a work permit and not legal status), and these people now have to continue hiding in the shadows, afraid of deportation and separation of their families. See here for a great breakdown of what DAPA is (and what it isn't). Also see here for a great blog post on the Supreme Court's website.
2. The refusal of Congress to confirm President Obama's nomination of Justice Garland to the Supreme Court. Garland is pro-immigration and would have been a deciding vote in our favor. He was nominated over a month before the hearing in April...plenty of time to confirm the appointment and get him on the bench to hear this (and other) very important cases.
3. Texas' standing argument was, at best, very thin. Their only real complaint was that it would cost money to have their DMV's process driver's licenses for those that get the EAD's, yet they decided, as a matter of policy to incur those costs to their state to improve safety, etc. (They could just issue licenses without tests, exams, etc)
4. We now have to wait to see if (a) other immigrant-friendly states join in on the district-level lawsuits to see if they can obtain their own ruling allowing people to apply (this would be a logistical nightmare) or (b) Congress actually do their job and take the action that is so desperately needed so that others (States and President) don't feel forced to take action and, allegedly, violate the constitution.
The upcoming election will be critical for our hope to have some type of solution to this incredible problem. If you are US citizen make sure you are registered to vote and go out and vote in November. If you are not a citizen contact me to see if you are eligible to become one!
