Section 1 of the Criminal Law Act 1977 governs the law on conspiracy. In simple terms, it is defined as an agreement between two or more persons to commit any criminal offence. The offence itself need not be carried out. It is the agreement and the intention behind that agreement that forms a conspiracy.

In the modern era where technology is commonplace amongst most, prosecuting authorities will now seek to establish the existence of a conspiracy by way of telephone attribution, mobile phone data, mobile phone call traffic patterns and cell site analysis.

The most commonly charged conspiracy cases tend to link in with the following offences:

  • Murder
  • Firearms (Usage, Supply and Possession)
  • Violence (Kidnap, Blackmail and Section 18 GBH/ Wounding)
  • Drugs (Importation, Supply and Production)
  • Robbery
  • Fraud
  • Money Laundering

Richardson Lissack are specialists in representing clients who have been charged with conspiracy offences, with our team of lawyers being involved in the following high-profile cases:

  • R v D (Operation Berbice) A multi handed case charged as a conspiracy to murder in relation to a failed assassination plot.
  • R v K A multi handed case charged as a conspiracy to murder in relation to the killing of a rival gang member.
  • R v M (Operation Optica) A multi handed case charged as a conspiracy to possess a firearm with intent to endanger life that resulted in several shootings.
  • R v C (Operation Macaroni) A multi handed case charged as a conspiracy to commit GBH and conspiracy to possess a firearm with intent to endanger life that resulted in a non-fatal gangland shooting.
  • R v A (Operation Bizarre) A multi handed case charged as a conspiracy to import 20 tonnes of cannabis from the Netherlands to the UK stored under piles of frozen meat in cold stores, valued at £80 million. It was the largest seizure of its kind in the UK at that time.
  • R v R (Operation Yonside) A multi handed case charged as a conspiracy to supply cocaine and cannabis throughout North Wales, Merseyside and Manchester. The conspiracy was described by the Judge as one of the most significant and sophisticated drugs conspiracies in recent times.
  • R v P & D (Operation Riptide) A multi handed case charged as a conspiracy to rob cash-in-transit security drivers that resulted in hundreds of thousands of pounds being stolen with use of firearms and other offensive weapons.
  • R v T (Operation Isidor) A multi handed case charged as a conspiracy to launder the proceeds of crime (money laundering) through a complicated web of property purchases utilising fraudulently obtained mortgages.
  • R v B (Operation Uzana) A multi handed case charged as a conspiracy to defraud amongst other offences of a conspiratorial nature. The fraud was valued at over £12 million and was one of the longest trials in UK history.

“I would like to say the service from Anthony was excellent. Whilst I see people, including my co-defendants getting frustrated with their legal team (ie. not being able to contact them and not getting questions answered), I have had a great service and was always satisfied from start to finish.”

“Kim’s always gone the extra distance in times of need and always been ever so easy to talk especially in times of stress. Kim’s very thorough and diligent in her work who’s judgement and opinion I’ll always trust. Kim’s always been readily available and if not - very prompt in getting back to me. I’ve recommended Kim to friends over the years and they’ve always thanked me in doing so as she’s provided them with the same level of care and attention.
