A European grouping of territorial cooperation (EGTC) is a European Union level form of transnational cooperation between countries and local authorities with legal personality.
EU Council Regulation 1082/2006 of 5 July 2006[1] forms its legal basis.
When an EGTC is formed its convention has to define the objectives and powers of the entity and it is limited by the respective powers of its members under their national law.
According to the regulation if an EGTC carries out any activity violating a Member State's provisions on public policy, public security, public health or public morality, or violates the public interest of a Member State, a competent body of that Member State may prohibit such activity on its territory or require those members which have been formed under its law to withdraw from the EGTC unless the EGTC ceases the activity in question.
Such prohibitions can not be used as an arbitrary means to limit cooperation under the regulation and are subject to judicial review.
