Once elected, the 135 Members of Parliament represent all the people of Catalonia, and not only those who voted for them. They represent Catalonia.

In order to allow them to carry out their functions effectively, they are granted a series of rights and guarantees, counterbalanced by specific duties.

The duties of Members of Parliament include:

• - Attending debates and votes of the Plenary Assembly and the working committees they form part of, and fulfilling their obligations as set out in the regulations.
• - Being members of at least one working committee.
• - Acting courteously and respecting regulations on the confidentiality of registers and on secret and confidential information, as well as regulations on order and discipline.
• - Declaring the professional activities in which they are involved and the goods they own.
• - Abstaining from using their position for the benefit of their own commercial or professional activities.

The rights of the Members of Parliament are:

• - To attend all Parliamentary sittings.
• - To participate in the debates and votes of the Plenary Assembly and those bodies of which they are members.
• - To propose amendments to any matter on which Parliament must make a decision.
• - To form part of a specific number of Parliamentary committees.
• - To benefit from preferable institutional and protocol treatment.

Guarantees for the actions of Members of Parliament are:

• - Parliamentary immunity, making those acts carried out by Members of Parliament as part of their Parliamentary functions exempt from judicial control. This legal protection reflects the idea that Members must be able to act freely during their mandate and can only be judged by the electorate, which may choose not to re-elect them. They can also be judged, however, by their party or coalition, which may exclude them from future electoral lists. During their mandate, Members of Parliament also benefit from immunity in that they cannot be arrested unless caught in flagrante delicto, thus preventing them from arrest for hidden political reasons.
• - Special privileges, by which they can be judged only by the Supreme Court of Justice of Catalonia or, outside the territorial jurisdiction of the Generalitat, by the Spanish Supreme Court.
• - Parliamentary allowances, for their dedication to Parliamentary work, which obliges them to restrict their professional schedule or commitments, or even to give up their employment, in accordance with the legislation concerning incompatibility.
