What Features of the Constitution Make it Difficult for Government to do or Achieve Anything

The separation of powers in the constitutions that prevent government from having his way to take a decision and implement it. The reasons that the constitutions has apportion the decision making process and it subsequent implementation among the three arms of government. The executive may introduce a policy statement in the form of a deal to congress but whether that policy can see the light of the day depends on the approval or other wise of congress. This means that, if congress is not in agreement with the government it will shut down the policy statement which has been introduced. The adjudication process is also entrusted to the judiciary such that if the president or any member of the executive does something or decides to do anything, the government action can be challenge in the supreme court and if the court comes with a determination, that the government action is unconstitutional it will order the government to seized and desist from taking such action. However, there are certain areas in the constitution which give the power to the executive to tale a decision and implement it. Example, the power to wage war. But even here the government will still have to forward to congress the budget on the war. In my opinion the constitution should remain the same.
