One big win and three defeats for Trump in dramatic day at Supreme Court

On the second-to-last day of Supreme Court decisions for this term, the justices delivered a big win for Donald Trump. But beneath the headline-generating ruling on expansive presidential power, the court gave some indications that this particular president may not always get what he wants – and the three liberal justices may have a few unexpected allies amongst the six conservative justices on the high court.Here's a look at the three biggest takeaways from an eventful Monday morning for America's judicial branch.1. Sweeping presidential authority over 'independent' regulatorsNearly 100 years ago, the Supreme Court ruled unanimously that Democratic President Franklin Delano Roosevelt did not have unchecked power to replace commissioners on regulatory agencies set up by Congress to be insulated from presidential authority.On Monday, facing a challenge by Republican Trump, the court decisively scrapped that precedent."Subordinates who exercise the president's power are subject to removal by him," Chief Justice John Roberts wrote in the majority opinion. "Then, and only then, can they remain accountable to the president, and the president to the people."In this ruling, the court's justices divided into familiar groupings. All six conservatives, three of whom were appointed by Trump, found in favour of the president. The three liberal justices, all appointed by Democrats, dissented.
