May I draw attention to the
Privacy and Electronic Communications Regulations 2003.
Regulation #10 enables the regulatory enforcement of the right to privacy in respect of one's own provider.
Regulation #13 enables that provider to ensure that it is respected by others, so that it may comply with regulation #10.
Regulation #14 covers the ability to provide anonymous location information.
Regulation #16 covers calls to emergency services.
To my mind, any provider who has not ensured compliance with blocking of caller id by all those to whom calls are connected is failing to comply with regulation 10.
CommentsFans of the European Union may be interested to note that these regulations are the UK implementation of Articles 8 and 9 of the
Directive on Privacy and Electronic Communications - 2002/58/EC passed by the European Parliament and the Council on 12 July 2002.
The legally minded may wish to note that Ofcom's General Condition 16 requires that provision of Calling Line Identification Facilities is made "in accordance with the requirements of Relevant Data Protection Legislation." (The latest version of the General Conditions is found
here)
An alleged breach could therefore be investigated by Ofcom, or by the ICO, which enforces the PECR. As the regulation applies to telcos, this would fall most naturally to Ofcom.
(As an aside from the matter under discussion, if one reads regulation 15 (3) in passing, it may be of interest to note that until November 2003 Oftel / Ofcom was not regarded as a "person with a legitimate interest" by BT. That was changed, so that the necessary evidence to start taking action against Silent Callers could be supplied to Ofcom.)
