The Model Rules of Professional Conduct were developed by which organization?

The Model Rules of Professional Conduct were developed by the American Bar Association (ABA), which is a key organization in the U.S. legal profession. These rules serve as a guideline for ethical conduct that governs lawyers' behavior and practice. They were adopted to provide standards for professional responsibility and have been influential in shaping legal ethics both within states that have adopted them and nationwide.

The ABA, being a prominent association for legal professionals, aims to uphold the rule of law and improve the quality of legal services. This involvement has made the Model Rules an essential reference for legal practitioners when addressing ethical dilemmas and maintaining professionalism in their work.

Other organizations mentioned do not have the same authoritative role in establishing foundational legal ethics as the ABA does. Thus, while they may contribute to legal discussions or advocacy, the ABA uniquely created and maintains the Model Rules of Professional Conduct.
