Ryanair has responded to the non-binding opinion of the European Court of Justice today, in the case of a passanger who is seeking compensation for travel disruption.
The woman incurred costs after she became stranded during the Icelandic ash cloud crisis. Ryanair refused to reimburse her, but the European Court said the airline should pay.
This evening, the airline said this was a test case which creates no potential or retrospective financial liability for Ryanair.
A Ryanair spokesperson said this case was taken in relation to future "extraordinary" events only and that they hope the final court decision will find in favour of Ryanair.
They have described as discriminatory European rules that say airlines have unlimited liability, even in extraordinary circumstances.
Earlier, Dublin MEP Emer Costello called for the urgent updating of EU air passenger rights legislation.
She said: "I understand this ruling now has to go back to the Dublin Metropolitan Court, but the opinion today...highlights the need for further legislation to strengthen passenger rights," she said.
