Abstract

 The clauses jeopardizing the interests of the counterpart commonly exist in the format contract. Depending on the absolutely dominating economic or legal status, the user of the format contract makes the clause ignoring the possibility of negotiation between both sides. Therefore, this kind of clause is vividly called the “overlord’s clause”. The existence of the “overlord’s clause” influences the stability of social economic order to a certain extent, violates the equitable principle and furthermore, goes against the building of a harmonious society.  The article studies the using system, the using measures as well as the making procedure of the format contract, and explores the managing method of it from a few sides so as to eradicate the “overlord’s clause”, nip its appearance in the bud and realize social justice and righteousness.
