According to Article 39 of the Contract Law of People's Republic of China (PRC), one party shall conclude a contract according to the principle of fairness, draw the attention of the other party to the terms exempting or limiting its liability in a reasonable way, and interpret the terms according to the requirements of the other party.
The so-called format clause refers to the reusable clause drawn up in advance without consultation with the other party in the process of concluding a contract.
Article 40. A standard clause is in any of the circumstances stipulated in Articles 52 and 53 of this Law, or if the party providing the standard clause exempts the main liability, aggravates the other party's liability or restricts the other party's main rights, the clause is invalid.
Therefore, if the e-commerce platform, as a party providing the format clause, exempts its main responsibility, aggravates the other party's responsibility and restricts the other party's main rights, the clause is invalid. If the platform unilaterally closes part of the authority of the merchant, it should be considered as restricting the main rights of the merchant, which is suspected of violating Article 40 of the Contract Law. You can negotiate with the other party, but if it fails, you can bring a lawsuit to the court where the other party is located.
