The music industry umbrella trade group U.K. Music has given its backing to suspension of Internet accounts of file-sharers "as a last resort," while Internet Service Providers (ISPs) have shown their strong resistance to any technical sanctions.

The consultation process on the U.K. government's proposals concluded on Sept. 29 and legislation to tackle file-sharing is set to be announced in November.

U.K. Music has given its backing to the graduated response scheme set out by Lord Mandelson, secretary of state for business, innovation and skills. The anti-piracy measures range from warning letters and technical sanctions to suspension of Internet accounts.

However, Charles Dunstone, chief executive of Carphone Warehouse, has said he is prepared to take the government to court over the proposals to oblige ISPs to take action against customers. Carphone Warehouse owns TalkTalk, which has 4.25 million broadband customers.

Dunstone said the proposal to suspend access for those suspected of file-sharing was a "guilty until proven innocent" approach, and said he would "resist any attempts to make [TalkTalk] impose technical measures on its customers."

U.K. Music disagreed with the proposal for an equal split between ISPs and rights holders on costs of notifications, preferring that rights holders pay for detection and ISPs to pay for communicating to their customers. But ISPs are even less happy about the costs involved.

BT said such technical measures would increase costs to the whole industry by £1 million ($1.6 million) a day, forcing all broadband consumers to pay an average £2 ($3.20) a month extra.

U.K. Music members are: Association of Independent Music (AIM), British Academy of Songwriters, Composers and Authors (BASCA), BPI, Music Managers Forum (MMF), Music Publishers Association (MPA), Musicians Union (MU), Phonographic Performance Ltd (PPL) and PRS For Music.

"We support government's proposals which would see ISPs send notifications and apply technical measures to impede and discourage the distribution of copyrighted content via unlicensed P2P networks and encourage the use of legitimate services," states the U.K. Music submission to the consultation.

However, it also states that the level of infringement needs to be treated accordingly.

"As an industry, we agree that a clear distinction should be made between how technical measures are applied to the casual infringer compared to how they are applied to the egregious or persistent infringer, with temporary suspension of broadband accounts being applicable only as a last resort against the latter," said U.K. Music. "Safeguards and functional definitions should be introduced to ensure that this distinction is made and maintained.
