art_38__para_1__2

3. A modification shall be considered to be substantially altering the subject matter of the contract where it renders the contract materially different in substance from the one initially concluded, namely where one or more of the following conditions are met: the modification introduces or removes significant conditions which, had they been part of the initial procurement procedure, would have allowed for the admission of other tenderers than those initially selected or for the acceptance of a tender other than that originally accepted, would have attracted additional participants in the procurement procedure, or would not have led to the selection of the winning tenderer; the modification significantly changes the economic balance of the contract in favour of the contractor in a manner which was not provided for in the initial contract; the modification significantly extends the scope of the contract.
