The E-Commerce Regulations
The E-Commerce Regulations
So, what legal protections are there for ISPs? The Electronic Commerce (EC Directive) Regulations 2002 (or the E-Commerce Regulations as they are commonly known), introduced a number of provisions setting out the circumstances where Internet intermediaries should not be held accountable for material which is hosted, cached or carried by them.
For instance, Regulation 17 provides that a service provider shall not be liable for unlawful or illegal content, sent or posted by any of its users, so long as the service provider does not initiate the transmission, does not select the receiver of the transmission and does not select or modify the information contained in the transmission.
