Legal analysis: under normal circumstances, it needs to be based on the agreement of both parties. Bidding is an orderly market competition transaction mode, and it is also a legal procedure to standardize the selection of transaction subjects and conclude transaction contracts. Since bidding is a kind of transaction, involving the activities of legal persons of both parties to the transaction, but there is only one legal representative of the company, it is impossible to do everything in the transaction process, so it is bound to assign others to handle it and authorize others to exercise their legitimate rights and interests. As a result of entrusting others to exercise their legitimate rights and interests on their behalf, the trustee needs to produce the legal documents of the principal when exercising his power, thus generating the power of attorney for legal persons. Generally, in the tender announcement, potential bidders will be required to submit the power of attorney of the legal person when they participate in the bidding registration, and the power of attorney of the legal person will also be required in the tender documents.
Legal basis: Article 9 of the Bidding Law of People's Republic of China (PRC), if a project subject to tender needs to go through the examination and approval procedures in accordance with the relevant provisions of the state, it shall go through the examination and approval procedures first and obtain approval. The tenderer shall have the corresponding funds for the project subject to tender or the sources of funds have been implemented and truthfully stated in the tender documents.
