The Contracting Authority can cancel the competition with immediate effect if there are 'justifiable reasons'. C.f. the Public Procurement Regulations § 25-4. The justificationfor the cancellation is extensive errors and deficiencies in the contracting authority's registration forms. Furthermore, the requirement specification is communicated so imprecise that it is difficult for tenderers to recognise what should be used as a basis for calculation. These errors and deficiencies as a whole mean that the tender contest has to be cancelled.
