As a result, death sentences against both defendants have now been lifted.
All parties acted on a pro bono basis throughout the two years the case has been running.
Newly-qualified assistant solicitor Julie Morris led the Ashursts team, personally undertaking approximately 200 hours work, all outside of office hours.
Norton Rose litigation assistant Sara Partington also undertook several hundred hours work in her own time, instructing Peter Knox of 1 Crown Office Row on behalf of defendant Ian Cauldero.
Ashursts instructed Peter Thornton QC of Doughty Street Chambers on behalf of Nigill Francois.
After a two-day hearing at the end of June the murder convictions of Cauldero and Francois were substituted with convictions for manslaughter.
Both teams will continue to be involved until after representations on sentencing have been made to the Court of Appeal in Trinidad.
Environmental lawyer Adrian Blomfield was also heavily involved on the Ashursts team.
