Michele Perrin v Jackie Walsh - Neutral Citation Number [2025] EWHC 2536 (KB)
The central issue before the Court in this application is how the surveillance evidence has been obtained, processed and disclosed and whether there are such significant flaws in the processes adopted by the Defendant’s agents that the Court should refuse permission for the Defendant to rely on such evidence. The law relating to surveillance evidence and the exclusion of such evidence- 9 I am told by counsel that they have not been able to identify any authorities that spec

Covert Recordings of Telephone Calls in Ireland
The situation in Irish law is complex, and is governed by at least three separate provisions – the Interception of Postal Packets and Telecommunications (Regulation) Act 1993, the General Data Protection Regulation (GDPR), and an individual’s constitutional right to privacy, plus their rights under European Convention on Human Rights. Is it illegal to record a phone call? Not necessarily. Under Irish law, it is not illegal for a person to record a call if he/she is party

Admissibility of Instagram Posts
In most jurisdictions, private Instagram posts are admissible as evidence provided they meet standard legal criteria for relevance and authenticity. The fact that a post is "private" (visible only to followers) generally does not create an absolute privilege against its use in court. Key Requirements for Admissibility For a private post to be admitted into evidence, the following must typically be established. Relevance: The content must directly relate to a fact in dispute,

Covert Surveillance by Private Investigators in Ireland
EXECUTIVE SUMMARY Irish courts accept such evidence where it is gathered lawfully, proportionately, and in response to genuine concerns - such as suspected exaggeration or dishonesty. However, any intrusion into a claimant's privacy must be justified, and covert surveillance without cause is likely to backfire. “The Role of Private Investigators in Personal Injury Litigation: A Vital Tool for Insurance Defence” A Blog by Damian McGeady (Partner) - Lacey Solicitors Link:

Videography, Photography and a Person’s Right To Privacy
The “law” in Ireland is a somewhat confusing mix of Constitutional, general Privacy, GDPR/data protection and Human Rights provisions. Different provisions are relevant dependent on whether it relates to an individual, State Agency/Gardai or Media/Press personnel. The law covering the use of photographs is particularly complex, with intellectual property rights coming into conflict with the rights to freedom of expression, privacy and data protection. It is important to under

This is generally allowed when necessary to process a claim, prevent fraud, or comply with legal obligations. However, this disclosure must be proportionate and, where a private investigator is acting on behalf of an insurer, a contract must be in place restricting the in

What is OSINT?
The proliferation of open-source data (OSD) – found across social media posts, self-published blogs, and other open-source repositories – is materially transforming the world of investigations. However, obtaining meaningful insights from the increasingly large volumes of publicly available data is the biggest challenge facing effective investigations today. What is OSINT? OSINT is a military intelligence term, continues to be a normal technique in counter-terrorism, counter

What DATA is Open Source DATA?
As stated previously “open source” refers to data that is readily available for public consumption. Rather than coming from a single location, OSD can be taken from a range of sources for use in OSINT investigations. It is not enough, however, to simply think of using OSINT. It must be done with intelligence and care. The internet is a highly valuable data source, but reliance on manual investigation methods risks overwhelming analysts and investigators with irrelevant or low

Benefits of Open Source Intelligence
OSINT has been widely utilised across government and military applications since as early as the Second World War, supporting investigations into global issues, including counter-terrorism and counter-proliferation. As many former government investigators enter the private sector, OSINT’s popularity in industries such as financial services has steadily increased. Many organisations now consider OSINT a key part of investigative best practice, thanks to the range of benefits

Ethics and Open Source Intelligence
Data ethics are an obvious concern. Beyond the clear moral imperative to investigate ethically, GDPR requires organisations to focus on data storage compliance. However, there are wider ethical considerations when it comes to data collection. It is essential that organisations instil ethics and data privacy within intelligence processes from the start. As OSINT is generated from publicly available information, it could be said to be more ethical than intelligence gathered f
