Which of the following events does NOT automatically dissolve a general partnership?

In the context of general partnership law, the expulsion of a partner does not automatically lead to the dissolution of the partnership. Instead, the partnership agreement may provide guidelines for the expulsion process and the remaining partners generally have the option to continue the business without dissolving the partnership.

In contrast, the other events listed can lead to automatic dissolution. For instance, the unlawfulness of the business activity means that the partnership is engaging in activities that are against the law, rendering it void. The insolvency of a partner often disrupts the financial stability necessary for the continuation of the partnership and can also trigger dissolution under certain circumstances. Lastly, a natural disaster affecting business operations may impact the viability of the partnership to continue its business, which could also lead to dissolution.

Thus, the nature of expulsion allows for continuity of the partnership, as it does not inherently disrupt the legal or operational framework of the partnership unless specified by the partnership agreement.
