According to Article 20 of the Regulations for the Implementation of the Government Procurement Law, if a purchaser or a procurement agency has one of the following circumstances, it shall be deemed as discriminating or discriminating against suppliers under unreasonable conditions:
(1) Providing suppliers with different project information of the same procurement project;
(2) The qualifications, technology and commercial conditions set are not suitable for the specific characteristics and actual needs of the procurement project or have nothing to do with the performance of the contract;
(3) The technical and service requirements in procurement requirements point to specific suppliers and products;
(4) Taking the achievements and awards of a specific administrative region or a specific industry as the conditions for extra points or winning the bid and closing the transaction;
(five) adopt different qualification examination or evaluation criteria for suppliers;
(6) Restricting or designating specific patents, trademarks, brands or suppliers;
(seven) illegal restrictions on the form of ownership, organization or location of suppliers;
(eight) to restrict or exclude potential suppliers by other unreasonable conditions.
In this case, you have the right to appeal, but you'd better be cautious. After all, this is a thankless thing. If someone controls the bidding, let the person who controls the bidding play. You can't play with others. I suggest not to get involved in that muddy water. However, if you have the strength to get authorization and confidence to bid well, you can also see how others play. If you really can't win, it's always good to study. No one knows the result until the end, you can fight for it.
