Proportionality Guide - 2nd revision
The European Procurement Directive of 2014 pays specific attention to the principle of proportionality. The Directive does not specifically indicate how to deal with this principle. The Dutch experience shows that contracting authorities have great difficulty in applying this principle. In order to help the contracting authorities, the Proportionality Guide was published following the introduction of the Dutch Public Procurement Act (Aanbestedingswet) in 2012. (januari 2020)
The Guide contains a detailed explanation of what the principle of proportionality means, or should mean, in all stages of the procurement procedure and in the terms and conditions of the contract.
