Two sisters got involved in a heated argument with another woman as they felt she had jumped the queue and taken their taxi, a court heard.
Denise (34) and Bridget Burnett (31) had been out celebrating Bridget's boyfriend's birthday and had had too much to drink.
Judge Dermot Dempsey fined the sisters €150.
Denise, of Adare Park, Coolock, and Bridget, of Ribh Road, Harmonstown, both admitted a breach of the peace in Dublin Street, Swords.
Gda Michael McCallion told Swords District Court he was returning to Swords Garda Station with a prisoner in the van at around 3.30am on February 19 when he saw a taxi stopped outside the station.
Gda McCallion said there were a number of women beside the taxi and it appeared they were having an argument with a passenger.
He said a scuffle then broke out between one of the def-endants and an individual in the taxi.
Gda McCallion said the defendants were arrested and taken to the garda station where they were charged and later released.
Defence solicitor Fiona D'Arcy said the women had apologised to gardai the next day and were very sorry for their behaviour.
In relation to Denise Burnett, Ms D'Arcy said she was a stay-at-home mother with four young children.
The court heard her sister was working in healthcare and had no dependants.
Ms D'Arcy said the two women were out celebrating Bridget's boyfriend's birthday, they had too much to drink and became involved in a "silly altercation".
She said the pair felt agg-rieved because it was 3.30am, they had been waiting for a taxi and were next in line and believed the other woman had skipped the queue.
Ms D'Arcy also said she did not expect either of the two women to come before the courts again.
