The purchaser may decide not to allot a contract in one of the following cases:
1° It is not in a position to carry out the organisational, steering and coordination tasks itself;
2° Awarding the contract in separate lots is likely to restrict competition or is likely to make it technically difficult or financially more costly to perform the services.
Where a purchaser decides not to allocate the contract, it shall give reasons for its choice, setting out the legal and factual considerations on which its decision is based.
