I've uploaded a few documents recently which might be useful to anyone interested in issues of surveillance and interception of communications in Ireland.
First is the 2009/10 report of the Designated Judge responsible for monitoring the interception of communications and data retention:
Interception and Data Retention Annual Report 2009/10
Second is the 2009/10 report of the (different) Designated Judge responsible for monitoring covert surveillance:
Covert Surveillance Report 2009-10
Third is the Revenue manual setting out their understanding of their powers and duties in relation to covert surveillance, following the enactment of the Criminal Justice (Surveillance) Act 2009:
Revenue Surveillance Manual
(Many thanks to Mark Tighe for copies of the two judges' reports.)
