In a statement following the incident, the Council of The Bar of Ireland said issues of safety and security of barristers and all those working in the courts system are "an absolute priority".
The council said: "The Bar of Ireland will continue to actively engage with all relevant parties to ensure the protection of our members, and to facilitate a safe environment in which barristers can advocate on behalf of their clients."
Today's events earlier led to significant Luas disruption between Blackhorse and the City/The Point.
Services have since resumed - with operator Transdev telling passengers to expect delays on the Red Line.
