Members of the European Parliament (MEPs) are required to declare their financial interests or assets that could create a situation of conflict in the performance of their duties.
Members of the European Parliament are also required to update their declaration of financial interests every year.
In vote on March 11, 1999, about the report A4-0070/99 (Corbett, Gutiérrez Diaz, Palacio Vallelersundi) was adopted, numerous changes to the Rules of Procedure of the European Parliament designed to enable Parliament to adjust to the workings of the Amsterdam Treaty have been adopted: MEPs voted to tighten the rules relating to the declaration of financial interests.
The rule then goes on to state "if the member continues to refuse to submit the declaration after the infringement has been published,The President shall take action in accordance with Rule 124 to suspend the member concerned."
The original proposal to oblige members to declare all benefits above .100 was not approved, but another amendment designed to exclude members not completing the register from office in the Parliament did go through as did the amendment obliging chairmen of intergroups and other unofficial grouping to declare all forms of financial or secretarial support.
