On 4 October 2021, the Competition Appeal Tribunal (“CAT”) ruled on several procedural issues in the case between several claimants, including waste-management companies Suez and Veolia and car and machine tools business Wolseley and truck manufacturers that were involved in the truck cartel. The judge ruled that the case would be heard over a maximum of six months, starting 9 April 2024. Furthermore, the judge said that he was not persuaded that it would be appropriate to include second-wave claimants in the trial because of additional complexities because of the need for additional factual investigations for different witnesses and corporate groups.
On 5 October 2021, in another case management hearing in the present case, the judge ordered DAF to disclose market-wide leasing data. The claimants argued that they needed such data in addition to claim-specific leasing data in order to conduct a market-wide analysis. DAF opposed this but did not succeed, given the order of the judge. The CAT further ruled that test claimants had to provide disclosure on a stage by stage basis, starting with board papers and any annexes to those papers; that it should cover the entire period of the claim; and that it should be limited to those claimants at the trial.
