Simon Ash's practise consists principally of prosecuting cases involving serious and organized crime including homicide, fraud, human trafficking, drug trafficking, armed robbery, and serious sexual offences. He is known for his thorough case preparation, good judgment and persuasive advocacy. His effectiveness is reflected in the high rate of success achieved in the trials he deals with. He is often instructed for his ability to deal with cases involving difficult factual or legal issues, and for his experience of cases that require sensitive handling. He has dealt with several cases, in both the Crown Court and the Court of Appeal, against Queen's Counsel. He has experience of prosecuting cases, alone and as a leading junior, involving a large number of defendants. He has dealt with a number of high profile cases that have attracted national media coverage. He is on the CPS Level 4 Panel and the Rape Panel. His practise involves a significant amount of work for the Complex Casework Unit.
His experience in the Court of Appeal includes persuading the Court to quash convictions for rape (R v K  EWCA Crim 1006) and fraud (R v I [2012 EWCA Crim 217). In R v W, Times, March 30, 2011 Thomas LJ paid 'special tribute' to the way he had dealt with the case and said that he had "argued the matter with conspicuous economy and clarity".

The case involved two organised crime groups that were involved in a conspiracy to rob another organised crime group. The case also involved the delivery of a large quantity of drugs to one of the groups. The principal evidence in relation to these offences came from a police covert listening device that recorded conversations between members of the two groups.

Controlling or coercive behaviour. The defendant started a relationship with a woman who had three young children. He moved into her house after a short time. His behaviour was persistently controlling, aggressive, threatening, and violent. He prevented the victim from having contact with her friends and he kept her bank card. He was verbally abusive on an ongoing basis and made her feel worthless. He assaulted her repeatedly. He told her to kill herself several times.

R v B (2018) - Prosecution
Child Sexual Exploitation. Instructed by the Complex Casework Unit. The defendant, who was aged 15-16 during the relevant period, had posed online as a 16 year old girl (HP). He had set up false social media profiles. He used these to incite 75 boys aged from 7 to 16 to engage in pornography and to stream this to him or to record it and send it to him. He incited the boys to engage in penetrative and degrading acts. He sometimes incited two boys to engage in sexual activity with each other, including penetrative activity. There was no issue that the person posing as HP was guilty of CSE. The evidence against the defendant related to the use of his IP address and to evidence on his phone and on his computer associated with the use of the HP profiles. The defence was that someone else was responsible. The case therefore turned on expert interpretation of the phone and computer evidence. The defendant was convicted. He was sentenced to ten years and two months custody.

He was sentenced to life imprisonment.
R v D and eight others (2015) - Prosecution
Conspiracy to supply cocaine and other drug trafficking offences. Instructed by the Complex Casework Unit. The defendants were involved in a conspiracy to supply large quantities of importation grade cocaine. One group of defendants was operating at or near the top of the supply chain in the UK. The offending covered London, Hertfordshire, and Northamptonshire. Tick lists found at the homes of the principal defendants showed drugs debts amounting to several million pounds. The offending also involved the supply of heroin and the production and supply of cannabis at lower levels. The police found a drugs press at the home of one of the defendants (used to press kilo and half kilo blocks of class A drugs). The case involved a combination of surveillance, phone traffic, cell-site, ANPR, and DNA evidence to prove the defendants' involvement in the offending. All of the defendants were convicted.
R v B (2015) - Prosecution
False imprisonment and vaginal, anal, and oral rape of two young women. The defendant falsely imprisoned the victims for four and eight hours respectively. He raped each of them repeatedly. The rapes were sadistic and were intended to degrade and humiliate the victims. The abuse of each victim involved unusually disturbing sexual activity. The defendant photographed and video-recorded some parts of what happened. The case involved showing the jury the photographs and video recordings. The second victim's hands and feet were bound together throughout the eight hours during which the defendant falsely imprisoned her. The defendant claimed that he had paid the victims £500 each to let him act out his rape fantasies with them. The defendant was living in the UK in a false name. He denied his true identity in order to conceal a Polish conviction for rape. The prosecution obtained evidence from Poland to prove his true identity (by fingerprint comparison) and the fact and details of the conviction. The defendant was convicted after a trial that lasted for three weeks. He was sentenced to life imprisonment.
R v A (2014) - Prosecution
Human trafficking and rape. The case involved the trafficking of a young woman from Slovakia to the UK where she was sold and then repeatedly raped and beaten.

The case also involved the possession of extreme pornography, including a video of a young woman being raped at knifepoint. The case in respect of the human trafficking, rape and violence offences was stopped shortly before the trial because the complainant returned to Slovakia and declined to give evidence. The defendant was convicted of the extreme pornography offence.
