Legal certainty is a simple necessity for every tendering process. Even small mistakes can require the tendering procedure to be repeated or establish entitlement to damages claims for excluded tenderers. The actual success of a public procurement procedure – optimal service at the most convenient price – is determined in particular by the quality of the tender documents. They must clearly set out the contracting authority’s requirements, whilst also offering tenders scope for their own solutions. This is a tall order, especially for complex procurement procedures. Public procurement law leaves you significant scope for creativity, for example in determining the object of the matter put out to tender, the choice of the “right” tender procedure or the proper suitability and award criteria.
