Read the latest magazine Industry News Lead Three Lead Cartel Company Directors to be Disqualified 10 March 2021 THE CMA HAS secured the disqualification of three lead cartel company directors, after finding they broke competition law by forming a cartel in the construction industry. This move follows an investigation by the Competition and Markets Authority (CMA) into two of the UK’s largest suppliers of rolled lead, Associated Lead Mills Ltd (ALM) and H.J. Enthoven Ltd (trading as BLM British Lead), which are based in Hertfordshire. Rolled lead is used mainly in the roofing sector. The companies, which together account for a sizeable proportion of UK rolled lead supplies, admitted last year to forming an illegal cartel. This included breaking the law four times by colluding on prices, sharing the rolled lead market by arranging not to target certain customers, and arranging not to supply a new business because it risked disrupting the firms’ existing customer relationships. Each of the arrangements included exchanges of competitively-sensitive information. As a result, the companies were fined £1.5m and £8m respectively. Lead Cartel Directors Reflecting the serious nature of the breaches and the directors’ involvement, the CMA has now secured the disqualification of Jocelyn Campbell (BLM), Graham Hudson and Maurice Sherling (ALM). All were directors at the time the illegal cartel activity took place. Jocelyn Campbell also sought to conceal his communications with competitor businesses. He was using a different mobile phone from his main one, in the period from December 2016 until the launch of the investigation in July 2017. This only came to light when the CMA seized the phone. Maurice Sherling admitted to suspecting that ALM was breaching competition law and receiving competitively-sensitive information from a competitor (Jocelyn Campbell of BLM) but doing nothing to stop it. Jocelyn Campbell will be disqualified for 6.5 years, Graham Hudson for 4 years and Maurice Sherling for 3 years. Illegal Anti-Competitive Practices Michael Grenfell, Executive Director of Enforcement at the CMA, said: “It’s an important responsibility of company directors to ensure that their companies don’t engage in illegal anti-competitive practices, which can lead to higher prices for customers. “The CMA has clear evidence that these directors either knowingly entered into illegal arrangements and communications, or were aware of them and did nothing to stop them. That’s why these measures are needed. This should be a message to all directors – if your company breaches competition law, you risk personal disqualification.” Associated Lead Mills Ltd (ALM) is owned by International Metal Industries Ltd. H.J. Enthoven Ltd (trading as BLM British Lead) is owned by Eco-Bat Technologies Ltd. The disqualification of Jocelyn Campbell will begin on 18 March 2021 and the disqualifications of Graham Hudson and Maurice Sherling will begin on 30 May 2021. The CMA has issued a range of guidance to help businesses and directors understand more about how to comply with competition law, including compliance advice for company directors on how to avoid director disqualification and the competition law risk guide.
