The fund manager, on behalf of the fund, filed a dispute over a huge insurance claim and finally obtained a full victory judgment after seven years. This case involves complex legal relationships, including accounts receivable transfer and repurchase, contractual performance bond insurance liability issues, and criminal disputes, with relatively cutting-edge legal points. Procedurally, it involves the innovative use of unreal joint and several liabilities to handle multiple bases of claim rights, addressing relevant entities in a single case, which reduces the litigation burden on parties and poses extremely high challenges to lawyers’ professionalism. Meanwhile, the case went through a tortuous process: after the jurisdiction objection in the first instance, the High People’s Court revoked the designated trial; after the dismissal of the lawsuit in the first instance, it was revoked again by the High People’s Court; after losing the first instance, the High People’s Court remanded the case for retrial in the second instance; finally, it achieved a comprehensive victory in both the first and second instances, striving for the maximum rights and interests for the private equity fund client. This case is a model reflecting HongQiao ZhengHan’s top-tier dispute resolution capabilities and excellent client service capabilities.
