The 25-year-old man is alleged to have failed to notify gardai in Finglas on his new address on June 1.
He appeared before Blanchardstown District Court charged with failing to notify gardai of a change of address, contrary to Section 12 of the Sex Offenders Act, 2001.
State solicitor Caroline Deasy said the charge is summary only, meaning it can only be dealt with in the District Court.
Judge Hugh O'Donnell adjourned the matter until January.
Barred drunk wielded baton
A DRUNKEN man returned to a pub armed with a wooden baton after he had been refused entry.
Derek Magee (42), of Beneavin Road, Finglas, was shouting abuse at door staff when gardai arrived at the scene, Blanchardstown District Court heard.
Judge Hugh O'Donnell fined Magee €375 after he admitted public drunkenness and threatening behaviour outside The Full Shilling pub in Finglas on November 12. The father-of three is an unemployed van driver.
