Congressman from Tennessee recommended that six Carter-Ruck lawyers be banned from entering the United States because of their ongoing work on behalf of Russian oligarchs.

[9] Recent or current clients include the State of Qatar, Cubby Broccoli, Tesco, Rached Ghannouchi, Sir Elton John, Simon Cowell, Yusuf Islam (formerly Cat Stevens), Liam Gallagher, Jude Law, Prince Radu of Romania, Frank Bruno and Chelsea Football Club.

[13] Carter-Ruck was involved in legal action against Financial Times journalist Catherine Belton and her publisher HarperCollins over her book Putin's People.

[14] After Russia invaded Ukraine in 2022, Carter-Ruck said it condemned the invasion and that the firm would not represent individuals associated with the Vladimir Putin regime.

The complaints led to the publication of unprecedented front-page apologies to Kate and Gerry McCann, in addition to a payment of £550,000 in damages, which was donated to the fund to find Madeleine.

Carter-Ruck was instructed by commodities trader Trafigura over press coverage relating to the discharge of oil 'slops' from a Trafigura-chartered tanker in Ivory Coast in 2006.

Libel proceedings were brought against the BBC in 2009 after a broadcast of the current affairs programme Newsnight suggested that Trafigura's actions had caused a number of deaths, miscarriages and serious injuries.

The paper further claimed that this case appears "to call into question privileges guaranteeing free speech established under the 1688 Bill of Rights".

[28] The question subject to the gagging order was from Paul Farrelly, MP for Newcastle-under-Lyme: To ask the Secretary of State for Justice, what assessment he has made of the effectiveness of legislation to protect (a) whistleblowers and (b) press freedom following the injunctions obtained in the High Court by (i) Barclays and Freshfields solicitors on 19 March 2009 on the publication of internal Barclays reports documenting alleged tax avoidance schemes and (ii) Trafigura and Carter-Ruck solicitors on 11 September 2009 on the publication of the Minton report on the alleged dumping of toxic waste in the Ivory Coast, commissioned by Trafigura.

He suggested that Carter-Ruck and other media law firms probably saw the PCC as their enemy because "we can do the job for free and can provide a degree of discretion".

Despite their antagonistic relationship, Carter-Ruck publicly sided with Private Eye when the magazine lost a £600,000 libel case in 1989 against Sonia Sutcliffe, the wife of the Yorkshire Ripper.

Founder Peter Carter-Ruck was subsequently invited to attend a Private Eye lunch, and soon afterwards he asked whether the magazine could stop misprinting the first letter of 'Ruck' as an 'F'.
