Which of the following is true about the authority of partnership decisions?

The statement that decisions made must be for the benefit of the partnership is correct because it reflects a fundamental principle of partnership law, which emphasizes the fiduciary duty that partners owe to one another. This duty requires that all decisions made in the context of the partnership are intended to promote the welfare and success of the partnership as a whole, rather than serving individual interests.

This principle is grounded in the idea that partners should act in good faith and with loyalty to one another, as their mutual interests are intertwined. Decisions that do not align with the partnership's goals or that serve only one partner's interests could lead to conflicts and potentially harm the partnership's viability. Thus, the obligation to act for the benefit of the partnership is a cornerstone of the partnership relationship, ensuring that partners work collaboratively towards common objectives.

In contrast, while it is true that partners generally have the authority to make decisions in the course of running the partnership, such decisions should always reflect the partnership's best interests. The other options suggest misunderstandings of the nature and authority of partnership decisions. For example, the notion that every partner must agree on all decisions does not recognize the typical operational flexibility partners have, and claims that any partner can make decisions independently overlook the necessary collective interest considerations.
