A man who assaulted a school principal in a row over the disciplining of his son has been fined €750 at Kilrush District Court in Co Clare.

Martin James Tubridy, 55, of Quarry Vale House, Labasheeda, Co Clare, was convicted of assaulting school principal Liam Wolfe at the small rural school in Labasheeda in 2011.

Tubridy was dissatisfied with the way his eight-year-old son was disciplined by Mr Wolfe.

On 9 December 2011, Tubridy arrived at the school.

When Mr Wolfe told him he could not deal with the matter at that time, Tubridy punched him in the face, causing him to have two black eyes, a swollen nose and a broken tooth.

The assault left Mr Wolfe shocked and dazed and was witnessed by another parent who was in the school at the time.

Tubridy denied the assault happened this way.

The matter had been adjourned by Judge Patrick Durcan, who urged mediation among the parties but no progress was made on that.

Finalising the case today, Judge Durcan said nobody was entitled to enter a school and assault a school principal, particularly the principal of a small rural school who is regarded as a leader in their community and deserves a level of respect.

He regarded it as a very serious offence and imposed a fine of €750.
