This course provides an overview of the duties imposed by law — and by conscience — on members of the legal profession to clients, witnesses, opposing parties, tribunals and the public. The course focuses on the Model Rules of Professional Conduct, which most enrolled students will need to absorb before they can be admitted to practice; philosophical and sociologicall insights into the professional responsibility of lawyers aid this study. We also examine the non-disciplinary law of professional responsibility, including legal malpractice, effective assistance of counsel, and sanctions for frivolous pleadings. Each student’s grade will be based on a final examination and a short paper (counting for one-third of the grade) describing and analyzing the student’s interview of a lawyer about an ethical dilemma that the lawyer encountered in practice.
