Lawyers for a political activist accused of assaulting a garda have asked for footage taken by gardai on a camcorder not to be deleted.
Stephen Bennett of Pearse Green, Sallynoggin in Dublin was one of three people arrested after protestors clashed with Gardai outside the European People's Party (EPP) Congress last month.
The attendance of German Chancellor Angela Merkel and other European leaders at the conference last month was marked by angry protests.
Two political activists and a German student were arrested after the anti-austerity demonstrations turned violent outside the Dublin Convention Centre.
Shane O'Brien, of Rathbourne Avenue, Ashtown and German student Jennifer Rieck have been charged under the public order act.
Co-accused Stephen Bennett of Pearse Green in Sallynoggin is facing three charges - including the alleged assault of a garda.
As is common practice, the garda intervention was recorded on a camcorder and lawyers for Mr. Bennett have asked for the footage to be preserved.
All three have been remanded on continuing bail to appear in court again on various dates over the next two months.
