Posso estar enganada, mas essa cláusula não pode ser traduzida à letra. Porém, seria necessário ter mais algum contexto.

Segundo o que tenho traduzido de "contratos bilingues", no geral, essa cláusula-tipo (PT) ou padrão (BR) é chamada de "Língua" ou "Idioma".

A boilerplate conflict clause, sometimes referred to as a priority or prevail clause, which offers various options for determining priority between conflicting agreements, or between parts of agreements.

It is important to recognise this and to determine which version will prevail in case of inconsistencies or contradictions between the two. The following provision on the prevailing version in case of a translation of the contract:

Language.

This Agreement has been drawn up in the English language. In case of discrepancies between the English text version of this Agreement and any translation, the English version shall prevail.

Prevailing language clauses for better or worse

The risk of contradictions between the English and Chinese text is often attempted mitigated by including a so-called "prevailing language clause" wherein it is stated that e.g. the English text shall prevail in case of contradictions with the Chinese text. This is a good starting point, but may create a false sense of security.

For example, the Chinese text of the prevailing language clause may contain the opposite regulation, i.e. stating that it is the Chinese text that shall prevail in the event of contradictions with the English text.

Another example is that the prevailing language clause in English and Chinese are alike, but that other regulations in the Chinese contract text contain explicit wording that the Chinese text shall prevail in the event of contradictions.

These types of situations can lead to great uncertainty in terms of which language version shall prevail. In the event of a lawsuit before Chinese courts or arbitral tribunals in such contradiction of language cases, one should be prepared that Chinese judges will let the Chinese language version prevail.

Aqui encontra exemplos de cláusulas-tipo, inclusive as "Law and Jurisdiction, Governing Law, Applicable Law ou Law of agreement", ou seja, "eleição do foro e/ou da jurisdição competente e escolha da lei aplicável" (pergunta que o Rodrigo fez anteriormente):

Construction- É a cláusula que prevê os critérios para a interpretação contratual considerando-se quem os redigiu.

Ex: " In the event of a dispute hereunder, this Agreement shall be interpreted in accordance with its fair meaning and shall not be interpreted for or against any Party hereto on the ground that such party drafted or caused to be drafted this Agreement or any part thereof, nor shall any presumption or burden of proof or persuasion be implied by virtue of the fact that this Agreement may have been prepared by or at the request of a particular Party or his or her counsel.

O contrato bilingue serve para facilitar o negócio, para que ambas as partes tenham a certeza daquilo que estão a assinar, no entanto, o contrato não é legalmente válido nas duas línguas. Neste tipo de contratos, no final, deve existir uma cláusula que informa que o contrato é bilingue em, por exemplo português e inglês, e que informe que em caso de disputa, uma das línguas (geralmente de quem redige o contrato) prevalece sobre a outra. Ou seja, trata-se de uma facilitação, mas é crucial que esteja descrita a versão (língua) válida para tribunal.
