On 27 November 2013, a trial of the former couple's two personal assistants, Italian-born sisters began in R v Grillo and Grillo. The Grillos were accused of fraudulently using the credit cards of Saatchi's private company. During court proceedings in early December, the sisters claimed that Lawson had permitted their use of the credit cards in exchange for their silence regarding her drug use. Questions regarding Lawson's drug use were allowed by the judge as part of the sisters' "bad character" defence. Lawson admitted to taking cocaine and cannabis but denied she had been addicted, stating, "I found it made an intolerable situation tolerable." On 20 December 2013, the two sisters were acquitted. Scotland Yard said that Lawson would not be investigated over the drug allegations.
