The petitioner, a member of and steward for the Service Employees International Union, appeals the denial by the Superior Court (McHugh, J.) of his motion to quash the State’s subpoena requiring him to testify before a grand jury. We affirm.
The trial court’s order recites the following facts: The petitioner is employed as a State Correctional Officer. On or about September 15,2005, a psychiatric social worker employed by the New Hampshire Department of Corrections (DOC) sought union representation with respect to allegations that he had carried contraband into the prison. The petitioner investigated the allegations in his capacity as the social worker’s union representative, interviewing the social worker and several other individuals.
The State subpoenaed the petitioner to testify before the grand jury as to what the social worker and others told him during his investigation. The petitioner moved to quash the subpoena on the ground that his communications with the social worker and others were protected by a privilege between a union representative and a grievant. The trial court declined to recognize such a privilege and denied the petitioner’s motion to quash. The trial court did not address the petitioner’s alternative argument that the subpoena violated the Contract Clauses of the New *559 Hampshire and Federal Constitutions. See N.H. CONST, pt. I, art. 23; U.S. CONST, art. I, § 10. This appeal followed.
Before addressing the merits of the petitioner’s appeal, we begin with new assertions he made at oral argument. At oral argument, for the first time, the petitioner argued that the subpoena violated the social worker’s rights under
Garrity v. New Jersey,
Assuming, without deciding, that the petitioner has standing to raise an argument based upon the social worker’s
Garrity
rights, we decline to address it because: (1) he did not brief it,
see State v. Scovill,
We also do not address the petitioner’s contention, made for the first time at oral argument, that we should expand the attorney-client privilege to include communications between union stewards and union employees.
See Walker v. Huie,
The petitioner first argues that the trial court’s ruling violates the privilege for confidential communications between a union representative and union employee as recognized by the New Hampshire Public *560 Employee Labor Relations Board (PELRB) under RSA chapter 273-A (1999 & Supp. 2006). See New Hampshire Troopers Association v. New Hampshire Department of Safety, Division of State Police, PELRB Decision No. 94-74 (August 31,1994). While he concedes that the PELRB has not recognized this privilege outside of the context of an unfair labor practice charge, he asserts that the PELRB’s rulings in this area “serve as sufficient grounds to overrule the trial court.”
The PELRB has ruled only that an employer engages in an unfair labor practice when it compels a union representative to disclose confidential communications with a union employee. In New Hampshire Troopers Association, a police trooper contacted his union representative and told him of an incident in which he had been involved and that he believed would lead to discipline. Id. at 2. The trooper asked his union representative for assistance in contacting the union attorney and president. Id. Thereafter, the union representative’s superior questioned him about what the trooper had told him; the union representative answered the questions asked of him. Id. The purpose of the questioning was to aid the employer in the anticipated disciplinary procedure involving the trooper. Id. at 3.
The PELRB ruled that the employer committed an unfair labor practice by questioning the union representative about what the trooper told him. Id. at 5. As the PELRB explained, “In pursuing its disciplinary investigation, the Division of State Police has all of the options it might exercise under its managerial prerogative. This does not extend to allowing the employer to interfere with the Union in its role as representative of the individual member accused of misconduct.” Id.
The PELRB’s ruling in
New Hampshire Troopers Association
comports with rulings by the National Labor Relations Board (NLRB) and Federal Labor Relations Agency (FLRA).
See Cook Paint and Varnish Company,
The FLRA reached a similar conclusion in
U.S. Department of Treasury,
We disagree that the PELRB’s rulings in the context of unfair labor practice charges provide a basis for recognizing the existence of a privilege in the context of a grand jury proceeding. As another court has noted with respect to the privilege recognized by its state public employment relations board, the kind of privilege established by the PELRB “is strictly limited to communications between a union member and an officer of the union, and operates only as against the public employer, on a matter where the member has a right to be represented by a union representative, and then only where the observations and communications are made in the performance of a union duty.”
City of Newburgh v. Newman,
The petitioner has cited “no case in which a federal or state court has ruled that some form of union privilege bars a prosecutor or grand jury from inquiring into conversations between a union member and his union representative.”
In re Grand Jury Subpoenas Dated January 20, 1998,
New Hampshire Rule of Evidence 501 recognizes that the court has the inherent power to “develop new rules of privilege on common-law principles in cases coming before it.” N.H. R. Ev. 501 Reporter’s Notes. “Consideration of the creation of a new privilege must begin with the premise that all privileges are exceptional, and are therefor[e] to be discouraged. The investigation of truth and the enforcement of testimonial duty demand the restriction, not the expansion, of these privileges.”
Dixon v. Rutgers,
We must be particularly “circumspect about creating new privileges based upon perceived public policy considerations.”
In re Grand Jury,
For the above reasons, “with very limited exceptions, federal courts have generally declined to grant requests for new privileges.”
Pearson v. Miller,
Professor Wigmore has described four criteria that may be useful when analyzing whether to create a new evidentiary privilege:
(1) The communications must originate in a confidence that they will not be disclosed.
(2) This element of confidentiality must be essential to the full and satisfactory maintenance of the relation between the parties.
(3) The relation must be one which in the opinion of the community ought to be sedulously fostered.
*563 (4) The injury that would inure to the relation by the disclosure of the communications must be greater than the benefit thereby gained for the correct disposal of litigation.
8 J. WlGMORE, EVIDENCE § 2285 (McNaughton rev. 1961). Only if all four of these conditions are satisfied should a privilege be recognized. Id.
Applying these principles to the instant case, we decline to recognize a common law privilege that shields communications between union representatives and union employees from a grand jury subpoena. Even if we were to assume that the first two prongs of the Wigmore test were met, the petitioner “has still failed to show that the union relationship is so highly valued by an ordered society that its confidences warrant protection even at the cost of losing evidence important to the administration of justice.”
In re Grand Jury Subpoenas Dated January 20, 1998,
Moreover, whatever state interest there may be in encouraging confidential communications between union members and their representatives is not so strong that, in our view, it outweighs the State’s interest in the grand jury context in having all relevant evidence of criminal conduct explored.
In re Grand Jury Subpoenas Dated January 20, 1998,
Under these circumstances, we cannot say that the need for the privilege is “so clear” and the desirable contours of it “so evident” that we feel compelled to create it.
In re Grand Jury,
*564
Finally, the petitioner contends that the trial court’s decision violates the State and Federal Contract Clauses.
See
N.H. Const, pt. I, art. 23; U.S. CONST, art. I, § 10. Part I, Article 23 of the New Hampshire Constitution prohibits the making of retrospective laws. A retrospective law is one that “takes away or impairs vested rights, acquired under existing laws, or creates a new obligation, imposes a new duty, or attaches a new disability, in respect to transactions or considerations already past.”
Opinion of the Justices (Furlough),
The petitioner’s reliance upon the State and Federal Contract Clauses is misplaced as they pertain to
legislation
that impairs contractual rights.
