Generally revise laws related to LLC operating agreements

LC 3626 updates Montana's laws governing limited liability company (LLC) operating agreements - the internal rules LLCs use to manage their affairs. It clarifies that operating agreements must follow specific interpretation rules (referencing Title 28, Chapter 3) and prohibits them from unreasonably restricting member rights, eliminating the duty of loyalty, or reducing the duty of care. The bill also specifies that certain major decisions - such as admitting new members, selling company assets, or dissolving the LLC - require all members' consent unless the agreement states otherwise. These changes directly affect LLC members and managers who draft or follow these agreements.
