The High Court has ruled that four pub owners should be compensated by their insurer for financial losses incurred as a result of the pandemic.
The decision could have a major knock-on effect for over 1,000 other publicans with similar policies.
Sean's Bar in Athlone, and three Dublin pubs - The Leopardstown Inn, Lemon & Duke and Sinnotts - sued FBD Insurance for what they claimed were "consequential and ongoing losses" arising out of imposed closures due to COVID-19.
FBD claimed they were not covered under its Business Interruption insurance.
They argued that it only covers local outbreaks, and not national pandemics.
But Mr Justice Denis McDonald disagreed.
In an electronic judgement handed down today, he found that the policy sold by FBD did cover the publican's losses.
How much they are liable for is still up for debate, and will be thrashed out in court at a later date.
At the outset of what turned out to be a lengthy hearing last year, the barrister for the Dublin pubs said the outcome could be the difference between his clients being able to stay in business or not.
These cases were seen as "test cases" and with over 1,000 other customers waiting in the wings.
This landmark judgement could have significant financial consequences for FBD.
