The difference between a committee and a board of directors is that the former is set up to address the duties of a specified administrational sector whereas the latter is set up for a public utility or other institution or a specific task.
The operations and duties of committees are specified in their respective regulations.
The Deputy Mayors are chairmen of the committees. Their members and deputy members are elected by the City Council from among the ordinary or deputy members of the City Council. The City Council appoints a deputy chairman among the elected.
The members and deputy members of board of directors are elected by the City Council, who also appoints a chairman and a deputy chairman from among the elected.
A representative of the City Board participates in each committee and board of directors in order to monitor the decision-making process. The Board representative has the right to speak at the meetings but not to vote.
