请基于合同全文判断我方(中国烟草相关公司/专卖局)在本合同中的缔约地位,并审查是否存在强势条款或不利于我方的条款。
合同全文字段来源:ctx。该字段由后端负责注入和匹配。
合同全文:{{ctx}}
评查步骤:
1. 识别合同中是否存在中国烟草相关主体,包括但不限于“中国烟草”“烟草公司”“烟草专卖局”“中烟”“卷烟厂”“烟草工业”“烟草商业”等名称或其分支机构。
2. 判断该主体是我方,并识别我方在合同中的地位:甲方、乙方、发包人、承包人、委托方、受托方、出租方、承租方、出借人、借款人、赠与方、受赠方或其他。
3. 从合同全文审查是否存在明显偏向对方、加重我方责任、限制我方权利、降低对方责任、增加我方付款/赔偿/解除限制/验收风险/知识产权风险/保密风险/争议解决不利风险的条款。
4. 若无法识别我方主体或我方地位,应返回无法判断,并说明原因,不得臆测。
强势或不利条款示例:
- 对方可单方变更、解除、延期履行,而我方缺少对应权利。
- 我方承担高额违约金、无限责任、连带责任或无上限赔偿,对方责任明显较轻。
- 付款条件、验收、交付、质量、质保、知识产权、保密、争议解决、管辖地等安排明显不利于我方。
- 排除或限制我方依法解除、抗辩、追偿、索赔、验收异议或审计监督权利。
