Consider the following points about the Presidential system of government of the American model:
1. The President and his ministers cannot become the members of the legislature. In case the President appoints somebody as his minister who is also a member of the legislature, he will have to resign his legislative membership before accepting the ministerial assignment.
2. Ministers do not attend the sessions of the legislature and though they may go and also speak in the House, they cannot vote. Again, the legislature cannot censure the conduct of the ministers, it can only initiate proceedings of impeachment against the President.
3. The President may send his messages to the legislature and the latter may, and may not, act according to the wishes of the Head of the State.
4. The bills passed by the legislature are subject to the veto power of the President who may exercise this power in case of bills not pertaining to his choice. The budget prepared by the President is submitted to the legislature that may pass it, or cut it wherever it so chooses.
