The DACA exception was initiated by President Obama via executive order, Congress would pass no law establishing it. The next president, Trump, issued another executive order cancelling the Obama order.
Folks complained and the case eventually went to the Supreme Court, which ruled 5-4 that president B could not cancel something ordered by president A without justifying it very thoroughly. The only way I could understand this decision is to accept that presidential executive orders have the force of law, which is nonsense.
Only legislatures can enact laws in this nation. President Obama ordered something because he could, President Trump cancelled it and was informed by the Supremes he could not. This is not equal treatment under the law.
Chief Justice John Roberts is off the reservation on this issue, voting with the liberals whose notion is to approve whatever makes people's lives nice, regardless of enacted law and constitutional strictures.
Roberts is a serious disappointment, having been seduced by the DC swamp. It appears he craves the approval of his peers in the law, most of whom vote D, worse luck. Bush appointees have proved iffy.
