I assume the Deputy is referring to section 6 of the Criminal Justice (Miscellaneous Provisions) Act, 1997.
This section allows gardaí, in respect of arrests other than those executed under a warrant, to give evidence by certificate of certain procedural matters, including evidence relating to arrest, charge and caution with the purpose of relieving them from the obligation of attending in person in court to give such evidence orally. The certificate is tendered in court by a Garda court presenter.
The Garda authorities have advised me that a Garda working group was established to assess the implications of these new provisions and that this resulted in a pilot scheme being developed to implement the provisions. This pilot scheme was initially confined to selected courts, specifically Bridewell courts 44 and 46, which process approximately 33% of all court cases emanating from the Dublin metropolitan region.
