With the support of the Ministry of Justice, the Master of the Rolls, Sir Anthony Clarke, asked Lord Justice Jackson to conduct a review of civil litigation costs. Aims include carrying out an independent review of the rules governing the costs of civil litigation and to provide recommendations in order to promote access to justice at proportionate cost.

The review commenced in January 2009 and the findings were presented in January 2010.^[9] Many of the resulting reforms were implemented as part of the Legal Aid, Sentencing and Punishment of Offenders Act 2012 (LASPO) in April 2013.^[10]
