Jacob Dyer

1995 Lincolns Inn

I am a member of the Criminal Team at 15 Winckley Square. I both prosecute and defend all types of serious crime. I have been a category 4 prosecutor since 2009 and work primarily in the Crown Courts of Lancashire and Cumbria.

I have experience of prosecuting and defending a wide spectrum of sexual offences and I am involved in the training of advocates in the questioning of vulnerable witnesses.

I have prosecuted multi-agency cases involving CPS/DVSA/Trading Standards. My regulatory work has included large-scale, cross-border tachograph fraud. I also have broad experience in prosecuting and defending serious road traffic cases, including fatal accidents.

I regularly prosecute trading standards cases on behalf of Local Authorities. I have particular experience in taxi appeals in the Crown Court and have advised Local Authorities on taxi licensing policy.


Notable Cases

My recent work includes the following;


2015 - 2016
Prosecuted "Operation Hive" (Carlisle Crown Court) - a multi-handed drugs conspiracy involving what was the largest seizure of heroin in Cumbria

R v Walton (York Crown Court) - defended wife of man charged with multiple offences of sexual and physical abuse committed against several children of the family. Secured acquittal on all counts of cruelty relating to sexual abuse, despite conviction of husband

R v Hammond (Barrow Crown Court) - successfully defended woman charged with causing death by careless driving

R v Handley - secured acquittal of man charged with cash in transit armed robbery. Allegedly committed on a business park in Preston using a shortened shotgun. The defendant's DNA was found on the headrest of the getaway car. In the 3 week trial, telephone evidence (cell-siting and contact) was relied upon by the Crown to establish the conspiracy. A detailed analysis of the telephone evidence enabled the prosecution case theory to be significantly undermined resulting in the defendant's acquittal.

September 2017
Successfully prosecuted Deputy VC of major university for £1/2m fraud.

June 2018
Secured convictions against 5 defendants in "Operation Cronus" - multiple / complex allegations of fraud, involving the setting up of bogus companies.

February/March 2019
Successfully prosecuted 3 defendants in "Operation Finglas" charged with conspiracy to falsify tachograph records.
