	Importantly the court decision was not based on alignment with the UK Procurement Act 2023 that came into force a day after the start of the proceedings. The new act gradually replaces the PCR15 and does give greater flexibility for suppliers to effectively be banned, and for them to be added to a national debarment list from future public procurement procedures. But this needs to be done so in response to specific breaches in the law or misconduct and an investigative process has to first be followed in which the supplier is allowed to make representations.
