DB 1: PARLIAMENTARY AND PRESIDENTIAL SYSTEMSThe United States of America and the United Kingdom are two fairly different states. The USA has a presidential system, federal and constitutional republic and also liberal democracy as forms of government, while the UK works with parliamentary, constitutional-monarchy and unitary state governance.In a parliamentary system the candidate must have had some kind of prior national political experience as the Prime minister is selected within the legislative together with the cabinet that helps him or her in coordinating the government, whereas in the U.S. it is not a requirement for the president to have past political experience as we understand from our previous discussions so far only Barrack Obama (President January 2009 – January 2017) and George H.W. Bush (President 1989 – 1993) had past political experience as presidents.Presidents in the United states cannot serve as part of the legislative branch as in representing a certain constituency, whereas Prime ministers can still serve in the legislative arm as representatives of their constituencies (Cheibub, 2007). Prime ministers can set and announce when the national elections will be held, He or She can dissolve the legislature and call for new elections, the U.S. president cannot set the dates for an election as it is fixed and put in the constitution as a complete term, He or She can also not dissolve the legislative bodies.As the president is voted in by the electorate and not the legislature He or She can reject a proposal made by a lawmaking body (the Legislature) and can also defend himself if faced by impeachment i.e. in the United States, Whereas in the United Kingdom the Prime minister and his government can be dispatched by a simple vote of no confidenceIn the Presidential system the Presidents chosen respect the electorate or the house representing the electorate whereas in the parliamentary system the Prime minister works under the parliamentary as they have the mandate and power to dispatch (Cheibub, 2007).ReferenceCheibub, J.

A disadvantage arises as the long lifetime appointments deny the justice process a chance to gain new ideas in ways of problem solving or conflict resolution.The supreme court has several Justices hence allows them all to hear the arguments on both sides and the legal reasoning behind them and finally come up with a decision that lacks bias (Perry, 2009). The disadvantage comes up when there are differing views among the Justices especially if they don’t come to an agreement as this will lead to a long appeal process before they can all come to an agreement.We are aware that every Supreme Court decision contains the vote and the opinion. If the Justices are not well aware of the current happenings or have their own personal beliefs then their decision (vote) towards the case being appealed may not be fit. As a result many other cases will be dealt with in the same wrong way as they will have passed their opinion (is the element of the decision). The opinion helps determine the way lower courts and the Supreme Court will decide similar cases in the future.Another advantage of lifelong appointed justices is that they have enough time to dig deep into the law and interpret it hence have a better understanding in solving disputes and cases (Greenhouse, 2012). I would change the way the court is appointed to a fixed term of service probably twenty years for the longest serving justices so that there would be room for fresh blood and a stream of new ideas every now and then.ReferencesPerry, B.
