Oct. 6 (UPI) -- The U.S. Supreme Court is expected to address a number of cases concerning executive power -- specifically on elections, tariffs and President Donald Trump's ability to fire the employees of independent agencies -- as begins a new term Monday in Washington, D.C.

The decisions the high court makes in the coming months are expected to say just how aggressively Trump can wield his presidential power without interference from lower-court judges. With a conservative 6-3 majority, three of whom were handpicked by the president, the Supreme Court's next rulings could majorly affect the president's current policy efforts.

Among this term's cases:

-- The Supreme Court will consider whether Trump has the ability to fire the employees of certain independent government agencies. This case stems from Trump's firing of Federal Trade Commissioner Rebecca Slaughter in September.
