After their court action last month forced ISP Eircom to initiate a three-strikes procedure against broadband users downloading music illegally, the four major labels are now trying to convince Ireland’s other broadband providers to do the same.

Irish Times says EMI, Sony (NYSE: SNE), UMG and WMG have written to companies including mobile operator 3 Ireland and hotspot outfit Bitbuzz warning of legal action within seven days if they don’t follow suit. The letter also hints of further action to come regarding the blocking of torrent trackers like The Pirate Bay.

After fighting the labels and the Irish Recorded Music Association (IRMA) in court for eight days, Eircom last month agreed to send two warning letters and then cancel service to customers downloading illegally. The labels said at the time they would take “all necessary steps to put similar agreements in place with all other ISPs in Ireland”—but the ruling only referred to Eircom. Now the labels are effectively claiming it set a legal precedent, just as the IFPI argues its legal victory in forcing three Danish ISPs to ban Pirate Bay access actually applies to all providers in the country.
