Two independent TDs who scaled a security fence at Shannon Airport and attempted to approach two military aircraft are due to appear in court on Wednesday.
Deputies Mick Wallace and Clare Daly have been summoned to appear before Ennis District Court after they were arrested at Shannon on July 22 last.
The pair got within 100m of a Hercules C130 transport plane which was parked on a taxiway protected by Irish Army personnel.
They were intercepted by airport police personnel and later arrested by gardaí.
They were taken to Shannon Garda station for questioning but were later released later without charge while a file was sent to the DPP.
They later claimed they entered the airport because former Justice Minister Alan Shatter "challenged" them to do so.
They said the former Minister told them to "produce the evidence" that US military aircraft using Shannon are breaching Irish and international law.
Shannonwatch, a group that monitors military aircraft movements at Shannon, has expressed disappointment that the State has decided to prosecute the TDs.
Dr Edward Horgan said: “They were there to verify whether the planes were in accordance with US Government assurances to the Irish Government on such matters.”
Deputies Wallace and Daly are due to appear at Ennis District Court on Wednesday.
