The sentencing of a Dublin teenager for attempted murder has been put back to allow his lawyers consider yesterday's landmark Supreme Court ruling on the questioning of suspects in garda custody.

Tadhg Costello (18) from Richmond Hill, Monkstown in South County Dublin initially denied trying to kill Josh Leahy in Dublin City Centre in the early hours of May 31st 2012.

The victim, aged 17 at the time, was stabbed six times when he and his friends were set upon by another group at Johnson's Court after leaving a nightclub on South William Street.

However Tadhg Costello changed his plea mid-trial at the Central Criminal Court following a ruling by Mr. Justice Paul Butler that his garda interview recordings could be used in evidence.

He was due to be sentenced today but his legal team have been given two weeks to consider yesterday's unanimous Supreme Court ruling on the inadmissibility of garda statements made prior to a suspect receiving legal advice.

Donegal man Raymond Gormley (29) of Glenwood Park, Letterkenny succeeded in overturning his 2007 conviction for the attempted rape of a mother of two as she slept in her bedroom.

He served a six year prison sentence.

His garda statements, which were made after he had requested legal advice but prior to his solicitor arriving at the garda station, were deemed inadmissible as evidence.

Yesterday Justice Minister Alan Shatter acknowledged the Supreme Court decision will have an impact on the manner in which criminal justice issues will have to be addressed.
