Fifteen people are due in Belmullet district court in Co Mayo later facing public order charges for protesting against the Corrib gas pipeline.
Most of the charges are connected with blocking Shell traffic during the early phases of the onshore pipeline construction.
Protestors believe the construction should not have taken place while there are still questions to be answered about the legality of the Corrib project.
An Taisce is pursuing a Judicial Review of An Bord Pleanála's decision to grant planning permission and two other consents for the onshore pipeline.
