JUSTICE HOBBS delivered the Opinion of the Court.
JUSTICE SCOTT does not participate.
The Colorado State Board of Accountancy (Board) appeals from a decision by the court of appeals allowing the accounting firm of Zaveral Boosalis Raisch (ZBR) to use the accountant-client privilege, see § 13-90-107(1)(f)(I), 5 C.R.S. (1997), to refuse compliance, absent the client's consent, with a subpoena issued by the Board. The Denver District Court interpreted exercise of the Board's subpoena power, see § 12-2-126(1)(a), 4 C.R.S. (1997), as an exception to the accountant-client privilege. In the absence of express legislative language creating an exception, the court of appeals declined to imply one. See Colorado State Bd. of Accountancy v. Zaveral Boosalis Raisch, 931 P.2d 498, 500 (Colo. App. 1996).(1) We agree and affirm.
I.
The Board received an unsigned letter alleging improprieties in the accounting practices of ZBR in connection with two casinos. The writer of this letter accused ZBR of violating accepted accounting principles and of preparing deficient auditing statements
