Gardaí to use gait analysis and voice recognition to identify suspects
will soon receive powers to use
artificial intelligence
to analyse the gait, voice and other physiological features of suspects during criminal investigation.
These biometric investigative tools will be used alongside
facial recognition
to identify suspects in serious offences and to locate missing people.
At first, investigators will only be able to use these powers retroactively, to process evidence already available to them such as CCTV and phone footage. However, further legislation is planned to allow these tools to be used in a live setting, alongside live facial recognition, in situations where there is an imminent threat to life.
Under the plans, gardaí will be empowered to use artificial intelligence to identify the physiological characteristics of suspects on recorded footage.

This includes computer programmes that can analyse the gait of a person - the unique way they walk - to identify them. Other programmes will be able to identify people based on their voices patterns.
There has been significant debate regarding the Government's plans to introduce facial recognition technology in recent years, with criticism coming from civil liberties and privacy groups.
However, this is the first time the Government has confirmed it will also legislate for other forms of biometric data in criminal investigations.
The upcoming legislation 'will provide the power to utilise biometric technologies generally', a
Department of Justice
spokesman said.
'This could include the use of physical, physiological or behavioural characteristics of an individual, such as face, gait or voice', he said, but will not include DNA analysis and fingerprints, which are provided for in separate legislation.
As technology develops, other potential forms of analysis will become available overtime. These include tools allowing suspects to be identified by other unique markers, such as the shape of their ears or the pattern of veins in their hands.
Technology is even being developed to identify people based on the movement of their eyes and the unique odours they give off. All of these types of biometric data are provided for in the EU's Artificial Intelligence Act which, according to the Department of Justice, which will form the basis for Irish legislation in this arena.
Artificial technology will be used to compare biometric characteristics and provide a percentage based assessment of whether they match.
Garda management has long been calling for facial recognition powers to analyse digital evidence, which is becoming more prevalent in criminal investigations.
Manually going through hours of CCTV to identify suspects 'is becoming unfeasible and ineffective', Commissioner Drew Harris said last year.
He was speaking in the aftermath of the Dublin riots, when gardaí had to manually process 22,000 hours of CCTV footage to identify offenders.
In response to queries, the department stressed the new powers will be based on a 'bedrock' of human rights and that trained gardaí will review all results produced by biometric technologies.
'At the moment Garda investigations can involve teams of gardaí spending months and months trawling through footage from CCTV, footage captured on a phone or from passersby.
'Biometric technologies will help An Garda Síochána carry out investigations quickly and efficiently and will save valuable Garda time. It will prove to be of particular assistance where time is of the essence in order to preserve a person from a threat of serious harm or a threat to their life or the lives of others.'

The department said the technology will also save gardaí 'from the harrowing work of poring over thousands or even millions of images and footage of child sexual abuse material'.

South Dublin councillors agree to cut local property tax by 7.5% for next four years
Members of South Dublin County Council have voted to reduce the Local Property Tax (LPT) by 7.5 per cent for the next four years. The annual charge on residential properties is used to fund services provided by local authorities. Each local authority may reduce or increase the rate of the tax in its administrative area by 15 per cent. The decision to cut the rate for the next four years was approved by members in a vote by a margin of 25 votes to 14. READ MORE The motion was proposed by Cllr Mick Duff (Independent), who said he had the support of other independent councillors as well as members of Fine Gael , Labour and Fianna Fáil . Mr Duff said the decision to reduce the tax until October 2029 would ease the burden on homeowners and give council chief executive Colm Ward certainty in his budgets for the coming years. The move comes in advance of changes to the LPT scheme proposed by Minister for Finance Paschal Donohoe . The changes include a revaluation to take place on November 1st, with these valuations applying next year and continuing for five years. However, while most house valuations are expected to increase, Mr Donohoe has played down the impact of the changes. He said about 96 per cent of properties would remain in their existing band, with the majority of property owners – those with properties valued at €525,000 or lower on November 1st – paying between €5 and €25 extra a year. Properties above that value, or properties which move up a band, will see a higher increase in their LPT charge. Mr Duff said the review of the LPT 'is going ahead anyway', but what councillors had done was to bring certainty to the annual debate over the charge. He acknowledged the initial aim was to eliminate the charge entirely over the coming years, but said 'that is now going to be [a matter] for the next council'. At Monday's meeting members were also told the council exceeded its social housing target of 1,821 new homes between 2022 and last year. In a progress report on the council's housing delivery action plan for 2022 to 2026, council staff said the figure for social homes came in at 1,825. Council staff said the number of new social homes due to come on stream by the end of next year was 3,700. The homes are being delivered through a range of initiatives including the local authority building its own homes, partnerships with approved housing bodies, through Part V of the Planning and Development Act and leasing. Councillors were told up to the end of last year the local authority had built 566 new homes and 15 were acquired as 'turnkey' properties – meaning they were ready to move into. Approved housing bodies had built 123 and obtained 528 as 'turnkey' properties. Part V of the Planning and Development Act, which allows the council to buy properties from developers at cost, delivered 593 homes.

Mother (54) should never have been convicted of sexually assaulting her children, court rules
A mother (54) should never have been convicted of sexually assaulting her three disabled children as she was subjected to an 'extreme' imbalance of power when she made inculpatory statements to a psychologist and polygrapher, the Court of Appeal has ruled. Allowing her an appeal against her conviction, Mr Justice Brian O'Moore said on Monday the only evidence against the woman were 'inculpatory statements which she made in truly extraordinary circumstances'. He noted the Director of Public Prosecutions (DPP) was not opposing the appeal, and a retrial will not be sought. The appellant had pleaded not guilty but was convicted by a jury, following a retrial in July 2024, of four counts of sexual assault against three of her sons - between January 1st, 2005, and March 25th, 2015. She was also convicted of one count of child neglect between August 3rd, 2008, and March 25th, 2015. She was sentenced by Judge Catherine Staines to eight years, with the final two years suspended, but had remained on bail pending her appeal. READ MORE 'One of the most heinous crimes is sexual abuse by a mother of her own children,' said Mr Justice O'Moore, adding the woman should never have been convicted. . He said to add to the unusual nature of the case, the statements were made not to gardaí but to a psychologist and a polygrapher retained by Tusla . 'The manner in which [they] conducted certain parts of the final two days of interviews did not meet the standards one would expect, to put it mildly,' said Mr Justice O'Moore. He said the woman was assessed and interviewed over five days in August 2015, before she made inculpatory statements on the final day. In July 2021, she was tried before the Circuit Court, where the judge ruled admissions made ought to be excluded as they were not voluntary. The trial judge directed the jury to return a verdict of not guilty. The DPP appealed this, with the Court of Appeal ruling the admissions ought not to be excluded. This decision was upheld by the Supreme Court, with a retrial then taking place. During the retrial, the psychologist accepted that statements made by the polygrapher could have been interpreted as inducements. The psychologist also accepted there was a risk the appellant may have made admissions to him on the basis she believed this was what he wanted. The trial judge said she had serious concerns about the voluntariness of the admissions, but she ultimately ruled she was bound by the decision of the Supreme Court and that the admissions made by the woman were admissible. Mr Justice O'Moore said neither the Court of Appeal nor the Supreme Court had available to it the revealing evidence of the psychologist given in the second trial. 'As these admissions constituted the only evidence against her, it follows that she should have been acquitted of all charges against her,' he said , ruling the court would allow the appeal.

Retired garda can challenge Garda Commissioner over loss of Irish-speaking allowance, court rules
A retired Donega l garda sergeant has been permitted by the High Court to challenge his former employers in a bid to restore his Gaeltacht allowance as he claims losses to his pension entitlements. Paul Wallace, of Burtonport, Co Donegal, is taking the action against the Garda Commissioner over what he claims is their failure or refusal to determine his January 2023 application to have the allowance restored. Mr Wallace is asking the court to declare that the alleged continued failure to restore or even decide the matter is 'unlawful' in that it breaches the respondent's obligation to determine financial issues. He claims this is preventing him from pursuing any internal appeal, which he argues is in breach of fair procedures. READ MORE Mr Wallace says in his court papers that he was sworn in as a member of the Garda in 1985, posted to Monaghan Garda station and was promoted to sergeant in November 1993 when he was moved to Glencolmcille Garda station in Donegal. He said he was transferred to Letterkenny in June 1997 and then to Bunbeg in November 2000. Glencolmcille and Bunbeg are in Gaeltacht areas in Co Donegal. Mr Wallace accepted the position of divisional crime prevention officer in November 2002 and was transferred to Letterkenny. There his role included giving interviews in Irish to print and broadcast media, with TG4 and Raidió na Gaeltachta having studios in Donegal, as part of a service to the entire county, including Gaeltacht islands inhabited by Irish speakers. At the time of his training, his competency in Irish was judged to be at 63 per cent, rising to 82 per cent in 2003. Mr Wallace was in receipt of the allowance for four years from 2003 and in 2007 and applied for its restoration in 2007 but was refused on the basis that Letterkenny was not designated as a Gaeltacht area at the time. In August 2020 Letterkenny was designated as a 'Gaeltacht service town' but Mr Wallace claims he had served the Gaeltacht community since 2002. He reapplied for the allowance in January 2023 but retired in March 2024 without, he claims, any update from Garda headquarters over his application. Mr Wallace took his Garda pension, which did not include his allowance, resulting in, he claims, the loss of €8,708.17 from his one-off gratuity payment upon retirement and €249.38 a month from his regular pension. He claims the Garda is under a duty to exercise statutory powers in a 'prompt and reasonable manner' in terms of the rights of people to fair procedures. 'On any analysis, the respondent [the Garda Commissioner] has not acted promptly or reasonably in failing or refusing to take the decision in issue,' he argues. At the High Court on Monday, Ms Justice Mary Rose Gearty granted the application for leave brought by Paul McGarry SC, for Mr Wallace, and adjourned the matter to October.
