Peter Collins, who was prosecuted in 2000, was not convicted of any criminal offence. Collins appealed to a Magistrates' court to have limits on his street trading licence removed. These limits, to which all traders are subject, allowed him to label his goods in imperial quantities only if metric quantities were also displayed no less prominently. In 2008, Nic Davison was served with an infringement notice for selling draught beer by the litre rather than pints, at his Polish restaurant in Doncaster. Trading Standards officers threatened Davison with prosecution, and called on him to change the glasses used in his restaurant. Davison refused, stating the supremacy of EU law in UK law in matters of weights and measures. The case against him was dropped. Davison had sought the help of then Prime Minister Gordon Brown and of his MP Ed Miliband. Pardon campaign UK regulations drawn up in response to EEC/EU weights and measures directives had required the use of metric units for certain activities, including sale by weight or measure in the retail trade of certain produce. Prior to 1 January 2000, these regulations applied to most pre-packaged food but on that date, they were extended to cover selling transactions where the product was weighed in front of the customer. The regulations permitted the equivalent imperial unit to be displayed alongside the metric unit as a "supplementary indicator". In 2007 the European Commission announced that for the cases where metric units were required, it had extended the option to also use imperial units indefinitely. These changes followed from public pressure, and concerns that phasing out dual-labelling would create a trade barrier with the United States, where dual-labelling is required. In response to the European Commission's announcement, there have been calls for a posthumous pardon for Steve Thoburn, who died after having his petition to the European Court of Human Rights denied. Despite an early day motion by Philip Davies MP, the pardon was denied on the grounds that an offence had been committed under the law which was in force at the time. The 2007 EU announcement was not about a change to existing (2001) legal requirements, but rather abandoned plans for a change in 2009. Moreover, the Office for Criminal Justice Reform claimed that even if the law were to be changed, there would still be no case for a pardon "as citizens are expected to comply with
