In the case of American Trial Lawyers Association, New Jersey Branch, et al. v. New Jersey Supreme Court (1972), the plaintiffs challenged a rule established by the New Jersey Supreme Court that required attorneys to disclose their clients' identities in certain circumstances. The U.S. Supreme Court ruled against the American Trial Lawyers Association and upheld the state court's rule on grounds of public interest and administration of justice. The federal court found no constitutional violation in requiring lawyers to reveal their clients’ names when those clients are involved in matters before tribunals or administrative agencies where representation must be disclosed under law or custom, or when necessary for financial audits related to attorney trust accounts.

The dissenting opinion in the case of American Trial Lawyers Association, New Jersey Branch, et al. v. New Jersey Supreme Court argued that the majority's decision to uphold a rule requiring attorneys to disclose their malpractice insurance status was an overreach of judicial power and violated attorney-client privilege. The dissenters believed that this requirement could potentially harm the relationship between lawyers and their clients by creating unnecessary suspicion or mistrust. They also expressed concern about potential misuse of such information by opposing parties in litigation, which could lead to unfair advantages or disadvantages during trial proceedings. Furthermore, they questioned whether it was within the court's jurisdiction to impose such a regulation on private practice attorneys who are not directly employed by the state judiciary system.
