■ Appointment of the Head of the Executive
The ability of the legislature to appoint the head of the executive allows the legislature an amount of influence over the executive branch. Therefore the presence of this appointment ability in a constitution indicates a degree of strength in the legislature. In some countries that have both a prime minster and a president, the legislature appoints one but not the other. Legislative strength is indicated where the legislature appoints the most powerful office in the executive.
