The Chief Executive of Killybegs Fishermen's Organisation said it members are enraged that the Government has enacted legislation that will see penalty points introduced for fishermen.
It has been a European Union legal requirement since 2012.
Seán O'Donoghue told RTÉ's Morning Ireland that fishermen have never been against the implementation of such a system, but they are concerned that you do not have the right to appeal this to the High Court, except on a point of law.
He said if you succeed in the High Court, your penalty points still stay on your licence, which he described as "unacceptable" and "not in accordance with fair and natural justice".
He said other jurisdictions, which have implemented this system, have allowed people to challenge it if necessary in their courts.
The penalty points system applies to the licence holder of a fishing vessel when a serious infringement of the Common Fisheries Policy occur.
He said when they saw it in the Programme for Government, they were very happy with the wording, such as needing a fair and reasonable penalty points system here.
He said fishermen were enraged, "that without any consultation whatever, the Taoiseach signed off on this highly controversial penalty".
He said they cannot understand how Taoiseach Micheál Martin signed this into law knowing that while in opposition in 2018, Fianna Fáil had the statutory instrument annulled in the Dáil for the first time in the history of the State.
He said the Supreme Court struck down a previous penalty points system that was not in accordance with their constitutional requirements and did not meet the criteria of fairness.
