农业公司承包土地违规改变土地用途，北京密云法院判决合同无效

Core Viewpoint - The article discusses a court ruling in Beijing's Miyun District that invalidated a contract due to illegal changes in land use, emphasizing the importance of adhering to land management laws for sustainable development [1][2]. Group 1: Legal Context - The case involved an agricultural company that illegally constructed a "management building" on a piece of wasteland originally designated for agricultural use, which led to a contract dispute with an individual named Li [1]. - The court confirmed that the contracts signed between the agricultural company and Li were invalid because they violated mandatory provisions of land management law by changing the original land use without proper approval [2]. Group 2: Financial Implications - The agricultural company claimed that the house built on the land was deemed illegal by the local government, thus the resale contract with Li should be considered void, and Li should return the difference in purchase price amounting to 60 million yuan [2]. - After the court's ruling, it was determined that Li must return the 60 million yuan difference after offsetting mutual obligations, as the civil legal actions were deemed invalid [2]. Group 3: Appeal Process - Li expressed dissatisfaction with the initial ruling and filed an appeal, but the second-instance court upheld the original decision [3].
