The Alcatel mandatory standstill period is a period of at least ten calendar days following the notification of an award decision in a contract tendered via the Official Journal of the European Union, before the contract is signed with the successful supplier(s). Its purpose is to allow unsuccessful bidders to challenge the decision before the contract is signed. It is named after a pair of linked European Court of Justice cases which are jointly known as the Alcatel case (Case C-81/98). Under EU law a statutory "standstill period" was introduced by the Remedies Directive as amended in 2007.^[1] Within the UK, it was introduced by the Office of Government Commerce in 2005 and remains within UK contract award legislation under regulation 87 of the Public Contracts Regulations 2015 ^[2] and regulation 86 of the Public Contracts (Scotland) Regulations 2015,^[3] even though the UK has now withdrawn from the European Union.

The timelines given below are the minimum (of at least 10 days) under the 'Alcatel' mandatory standstill period and show the days by which specific actions by the contracting authority (ie notify all tenderers of the award decision and the completion of any requested additional de-briefing) and by the tenderer (ie a request for additional de-briefing within the standstill period), and in order to comply with the minimum period before entering into a contract (assuming no legal challenges are formally notified).

Where a legal challenge has been filed in the High Court (Court of Session or Sheriff Court in Scotland), the starting of those proceedings "automatically" requires the contracting authority to refrain from entering into a contract until the proceedings are resolved or the court lifts the suspension.^[4] Regulation 96(5) in the UK regulations also stipulates that the court cannot issue an order lifting or modifying the suspension until the standstill period has ended.^[5]

Notes: - Depending on the day of the initial notification of the intention of the contract award decision, given the very tight timescales for the additional debriefing, it may be more practical to extend the end-date of the standstill period beyond the minimum of 10 calendar days.

- The 'traditional' de-briefing requirement (within 15 days of receiving a written request) remains where a tenderer does not seek an additional de-briefing within the first 2 working days of the standstill period. In any case, all tenderers can make formal complaints in Court within the standstill period regardless of having requested or received debriefing within the standstill period and Courts can agree to grant interim measures preventing contract award.
