An adapted procedure is one by which the purchaser freely defines the terms and conditions for awarding the contract, in compliance with the principles of public procurement and the provisions of this Book, with the exception of those relating to the obligations inherent in a purchase under a formalised procedure.
The purchaser may award a contract using an adapted procedure:
1° When the estimated value of the requirement, excluding tax, is less than the European thresholds mentioned in a notice annexed to this code;
2° Because of the purpose of the contract, under the conditions laid down by decree in the Conseil d’Etat;
3° When, even though the estimated value of the requirement is equal to or greater than the formal procedure thresholds, the value of certain lots is less than a threshold set by regulation.
