Not explicitly stated but probably unchanged from 1996: two players who tied for first would share the title, while in the case of a tie between three or more players, a tie-break (of unspecified form; probably progressive / cumulative) would determine a single champion.

Tournament review
Gerry Graham gave detailed round-by-round reports in CHESS IRELAND - NEWS, Mar-Jun 2000 (via the Wayback Machine). Mark Heidenfeld extended the family connection with the Irish championship, following in the footsteps of his father Wolfgang, Irish champion in 1958, 1963, 1964, 1967, 1968, and 1972. Colm Daly was seeking to become only the second person ever to win the Irish championship in three consecutive years (quick: who was the first?; still the only one!) but fell well short.
Interesting games
The defending champion on the ropes but manages miraculous draw (not without considerable help): McMahon, Daire – Daly, Colm ½-½
