The requirement for evaluation of initial proposals is found both in the systems that recognize ERAs as an optional phase and in the systems that recognize ERAs as a distinct method.

In the systems that recognize ERAs as an optional phase, general procurement rules address the provision of solicitation documents.

(c) A note concerning ERAs, including drafting materials (A CN.9 WG.I WP.40)

In the systems that recognize ERAs as an optional phase, general rules on the content and means of providing such a notice apply.

The right to reject all bids at the end of ERAs is explicitly provided in some ERA specific regulations.

In the systems that recognize ERAs as a distinct method, the bidding documents are provided at the time when the notice of the ERA is given.

In the systems that recognize ERAs as an optional phase, all tenderers who submitted admissible tenders are invited to participate in the ERA.

With respect to electronic reverse auctions, the Working Group recognized the reality of electronic reverse auctions and confirmed its willingness to consider the appropriateness of enabling provisions for the optional use of electronic reverse auctions in the Model Law.

The systems that recognize ERAs as a distinct method require, at a minimum, registration of prospective participants that involves, in particular, assigning an identification code and password to allow the participants to log in to the system to participate in ERA.

As regards electronic reverse auctions (ERAs), taking account of the increasing use of ERAs and the twin aims of harmonization and promotion of best practice, the Working Group concluded that the revised Model Law should contain provisions on ERAs.

The Working Group postponed its final decision on the question of whether non electronic reverse auctions should be provided for in the Model Law until it had before it draft provisions governing the use of ERAs (A CN.9 575, para. 65).

If we were to create a real market, it would become unpleasantly commercial a bit like those charity auctions where celebrities or tycoons donate the pleasure of their company for lunch with the highest bidder, except that the VIP pockets the money.
