Matthew Keliris-Thomas

Call 2019

‘He spotted an issue with the case in preparing it for sentencing that had been missed in previous hearings and was incredibly helpful and proactive’.

Matthew is an engaging and incisive advocate who is developing a strong track record of success in the Crown Court. He is an attentive and intelligent brief with the ability to cut to the heart of a case and make it engaging for a jury.  

Matthew accepts instructions both prosecuting and defending across the full gamut of criminal law including serious violent crimes, offensive weapons, domestic violence, sexual offences, fraud and dishonesty, drug offences and road traffic offences. He has also been successful for clients in proceedings relating to DVPOs, SHPOs and other orders. Matthew also has experience of appeal work in both the Court of Appeal and High Court.

Before coming to the Bar, Matthew was part of the National Crime Agency’s legal team. He advised on public and serious crime, particularly RIPA/IPA, data exploitation, EncroChat, modern slavery and police powers. Matthew then moved to the Attorney General’s Office to lead the Annual Review of Disclosure 2021/22, writing the subsequent Disclosure Guidelines 2022. During his time at the AGO Matthew was seconded for a period to the crisis team dealing with international prosecutions stemming from the Russian invasion of Ukraine.

R v SJH & Ors [2024] St Albans CC

SJH was accused of transferring assets stemming from a six-figure set of frauds allegedly conducted by her co-defendants. She was successfully severed from the trial after which continued representations to the Crown over a number of months led to an offer of no evidence.

R v ZA [2024] Luton CC

ZA was accused of an affray with two others whereby she had used a weapon to attack a group of neighbours. This was a ‘cut-throat’ case. ZA was acquitted by the jury after trial while her co-defendant was convicted. The third co-defendant had pleaded guilty at the first hearing.

R v LG [2024] St Albans CC

LG was accused of a dwelling burglary with two others and a fraud by false representation using credit cards stolen from the burglary.

Featured Immigration & Extradition cases

Slovakia v GS [2023] Westminster MC

GS was sought on an accusation warrant. The Slovakian authorities requested GS to be tried for Fraud. Matthew resisted the request for extradition and was successful on two grounds: Article 8 (Right to Family Life) arguing GS was caring for his unwell wife and s.21A Extradition Act that the punishment potentially faced in Slovakia was disproportionate.
