The invalidation of the retainer agreement is supported by sufficient credible evidence in the record. Although the Appellate Division’s concerns over the retainer agreement in this case are understandable, the ethical pronouncements issued in its opinion may have far-reaching and negative effects, not only on employment-law attorneys and attorneys handling fee-shifting claims, but also on their clients. Some of those pronouncements appear too broad and some unsound, and others are worthy of the deliberative process by which new ethical rules are promulgated by the Court. The Court addresses those issues under its constitutional authority to regulate the conduct of attorneys in this State, N.J. Const. art. VI, § 2, ¶ 3, and directs that an ad hoc committee be established to address the professional-responsibility issues discussed in this opinion. The Court expresses no ultimate opinion on the matters referred to the committee, which will report its recommendations to the Court.
