Final answer:
The Chairman of the Public Accounts Committee is elected by the members of the committee, which promotes democratic principles and accountability within the legislative process.
Step-by-step explanation:
In democratic systems, positions such as the chairman of a parliamentary committee are often filled by election among the members of the committee itself. This process ensures that the appointee has the confidence and support of their peers. In some contexts, such as in India, the convention is that the chairman of the Public Accounts Committee is appointed from the opposition, which provides a system of checks and balances. This helps ensure that the government is held accountable in its financial activities, as the PAC examines the expenditure of the government.
The appointment process of legislators and officials can vary from one political system to another. For example, the justices of the Supreme Court in the United States are nominated by the president and confirmed by the Senate. In other systems, like in the Parliament of the Bahamas, key figures like the governor-general, with consultation from the prime minister and the leader of the opposition, appoint members to positions of power such as the Senate. While this does not involve a direct election by the public, the democratic principle is upheld through indirect accountability since the leaders who make these appointments are themselves elected by the citizens and are responsive to political shifts and public opinion.
