Answer:
A duty is what you owe to your fellow human as a fact of nature, and an obligation is what has been imposed by contract or custom. Generally, one is “obliged,” or “obligated,” by agreement or because of having received a benefit. If you take candy from a store, you have an obligation to pay for it.
Another power to add to the list would be: Deciding the legality of executive orders.
An example would be Executive Order 13769, which was titled, "Protecting the Nation from Foreign Terrorist Entry into the United States." President Donald Trump signed this order on January 27, 2017, in the first weeks of his presidency. Commonly called the "travel ban," this order suspended travel to the United States from a number of countries with a majority Muslim population. The order immediately was challenged in the courts as unconstitutional. The Trump administration was compelled to replace Executive Order 13769 with a revised version that it hoped would stand up to court challenges, Executive Order 13780, signed in March, 2017.
