How long do complaint investigations typically take?


The time taken to close an investigation depends on the level of complexity of the case, but to get an indicator, you can look in the Publications section of the website to find the median time taken to close investigations by type, per quarter.

The time taken to close an investigation depends on a number of factors:

  • level of complexity of the case
  • type of investigation
  • time taken to receive information and evidence
  • cooperation and availability of witnesses and garda members
  • impact of operational matters
  • whether the file is sent to the DPP for a prosecution decision and whether the case goes to court
  • time taken to decide on disciplinary matters, where relevant, and whether the case goes to a Board of Inquiry
  • whether an appeal is made in relation to a finding or sanction.

In relation to disciplinary matters investigated by a Garda Síochána Investigating Officer, GSOC has little control over the time taken, but does issue reminders to the GSIO, in an attempt to ensure that cases are concluded without delay. If there is an excessive delay, there is an escalation process laid out in chapter 18 of the Protocols between GSOC and AGS, which we may resort to. If the investigation is unsupervised,  we may also decide to supervise it in a bid to get it completed.

You can get an indication of the durations of different investigation types in the Publications\Statistics section.

  • What happens following a referral under section 102?

    If a matter is referred to GSOC under section 102, GSOC must investigate, with a view to establishing the facts of the situation and clarifying whether it may have resulted from garda misconduct. In many cases, this will require a GSOC investigator or team of investigators to attend the scene of an incident and work closely with An Garda Síochána teams there. Read More

  • What should I expect if I am involved in a matter referred to GSOC?

    If you are involved in a matter which is referred to GSOC, you will most likely be aware of this fact at the time. Otherwise you may find out when you are contacted by a GSOC investigator working on the case and asked to assist in establishing the facts. Read More
  • Can GSOC investigate conduct of off-duty or retired gardaí?

    Sometimes. A complaint against a garda member can be admitted if it concerns conduct off-duty which would be likely to bring discredit on the Garda Síochána. Investigations following referral, or initiated in the public interest, can look into the conduct of off-duty gardaí. Read More
  • How is Local Intervention done?

    The Local Intervention process is aimed at resolving certain service-level types of complaints against members of the Garda Síochána at a local level without the need for the matter to enter a formal complaints process. Read More
  • What does GSOC do about false or misleading information?

    Section 110 of the Act provides for penalties by way of fine and/or imprisonment for any person who knowingly gives information that is false or misleading to the Garda Ombudsman. Where we believe that there is sufficient evidence that such an offence has been committed, we send a file to the DPP. Read More
