Core Viewpoint - The case involving Wang, accused of illegal business operations, achieved a significant breakthrough with the intervention of attorney Chen Sainan, who successfully argued for the non-approval of arrest by the prosecution, thereby protecting the legal rights of the client [1][3]. Group 1: Case Background - Wang was implicated in a case concerning his wife's supermarket, which was under investigation for allegedly illegally operating tobacco products, with the amount involved exceeding tens of millions [1]. - The sudden criminal prosecution placed Wang and his family in a difficult situation, as they faced both economic and mental pressures, particularly with an elderly mother requiring care and the supermarket nearing closure due to lack of management [1]. Group 2: Legal Strategy - Attorney Chen Sainan quickly engaged in comprehensive investigation and legal analysis, identifying three key breakthroughs: the supermarket held a valid tobacco retail license, Wang was merely a temporary helper without involvement in core business decisions, and the products sold were genuine cigarettes, causing no tax loss or consumer harm [2]. - A dual defense strategy was implemented, aiming for both acquittal and the request for non-arrest, with detailed legal opinions submitted to the investigation and prosecution authorities [2]. Group 3: Outcome and Implications - Through multiple communications with the authorities, attorney Chen effectively articulated the case facts and legal basis, leading to the prosecution's acceptance of the arguments and the decision to not approve the arrest, allowing Wang to return home to care for his mother [3]. - The successful outcome of this case highlights the importance of legal expertise, case analysis capabilities, and effective communication in the judicial process, reflecting the principles of subjective-objective unity and the restraint of criminal law in practice [3].
