The union appeals the circuit court's judgment holding that the Manitowoc County Sheriff was not bound by a collective bargaining agreement when he placed a deputy in a new position involving undercover drug investigation. Because we conclude that the sheriff created a new position involving duties that did not involve one of the constitutional powers of the sheriff, we reverse the judgment of the circuit court.
Deputy Elijah Humphreys was reassigned from patrol duty to undercover drug enforcement by the Man-itowoc County Sheriff, acting through his second-in-command. The sheriffs department listed the assignment as temporary, to last from six months to three years. However, the assignment meant a vertical move for the deputy, giving him the title of detective and an increase in pay.
*914 The union objected to the appointment. It claimed that the sheriff created a new position and awarded it to Deputy Humphreys without posting it, contrary to the terms of the collective bargaining agreement in effect between the union and the county.
The county responded that the sheriffs authority to assign deputies to the various phases of law enforcement derives from the Wisconsin Constitution and that the constitutional powers of the sheriff may not be abridged by a collective bargaining agreement. In the alternative, the county argued that temporary positions are not governed by the collective bargaining agreement.
The dispute was submitted to arbitration. The arbitrator found that, prior to the reassignment of Deputy Humphreys, no employee of the sheriffs department spent 100% of his or her time involved in drug investigations. The arbitrator concluded that the sheriff created a new position by having one employee perform drug investigation on a full-time basis with increased pay. The arbitrator found no merit to the contentions that the assignment was temporary, since the collective bargaining agreement between the parties defined "temporary" as a time period not to exceed six months, even if it is of limited duration. Thus, the arbitrator concluded that the sheriffs failure to post the position violated the bargaining agreement.
The county appealed and the circuit court vacated the arbitration award. The court concluded that "law enforcement" and "preserving the peace" are among the constitutional powers of the sheriff. The court reasoned that the sheriffs authority to assign an individual to a particular job within his law enforcement or peace-preserving responsibilities is constitutionally reserved to the sheriff and cannot be regulated by a collective bargaining agreement. The court concluded that no defer *915 ence was owed to the arbitrator's decision because it enforced an agreement that is void as against the public policy of upholding the constitutionally protected powers of the sheriff.
The issue before us is whether criminal investigation is a distinctive responsibility of the sheriff that is reserved to the sheriffs office by the Wisconsin Constitution. We certified this appeal to our supreme court, but the certification was denied. The appeal presents us with a question of constitutional law which we review
de novo
without deference to the circuit court.
See McManus v. DOR,
In 1870, the Wisconsin Supreme Court concluded that the office of sheriff is a constitutional office with characteristic duties and functions that may not be regulated by the legislature.
State ex rel. Kennedy v. Brunst,
Brunst
held that custody of the county jail was one of the sheriffs constitutional duties.

In 1982, the supreme court was presented with the question of whether the

of deputies was a constitutional prerogative of the sheriff.
Wisconsin Professional Police Ass'n v. County of Dane,
The court of appeals carried WPPA's conclusion a step further in
Wisconsin Professional Police Ass'n v. Dane County,
In the instant case, the circuit court relied on
WPPA
Ts conclusion that the nature of the job assigned determines whether a collective bargaining agreement can bind a sheriff. The circuit court considered drug investigation as falling under the sheriffs broad powers
*917
to "enforce the law" and "preserve the peace." The circuit court concluded that these were constitutional duties of the sheriff because
Brunst
acknowledged that "the duty of conserving the public peace" was one of the sheriffs duties,
Brunst,
We conclude that the circuit court ignored the holding of Buech and overextended the holdings of Brunst and WPPA I by interpreting them too broadly. The narrow holding of all three cases is that the constitutional prerogatives of the sheriff are limited to the immemorial, principal and important duties of the sheriff that were unique to the office of sheriff at common law and gave character and distinction to the office.
Applying that common holding to the facts of the instant case, we conclude that law enforcement and preserving the peace are not constitutional prerogatives of the sheriffs office because they were not unique to the office at common law. At common law, the sheriff shared the duty of conserving the peace with the watch and constable.
See WPPA I,
If enforcing the law and preserving the peace were constitutional prerogatives, then there would be no duty of the sheriff that is not constitutional. Everything the sheriff does can be characterized as enforcing the law or preserving the peace. Yet, Brunst, Buech and WPPA I clearly contemplated nonconstitutional duties of the sheriffs office in addition to the constitutional duties. They viewed the sheriffs office as having a limited constitutional nature.
Moreover, an expansion of the sheriffs constitutional duties to encompass everything the sheriff does would weaken the strong legislative policy in this state favoring arbitration and collective bargaining in the municipal context.
See Joint School Dist. No. 10 v. Jefferson Educ. Ass'n,
We acknowledge that at common law the sheriffs authority in conserving the peace and vindicating the law was the highest authority in the county.
See WPPA
1,
Investigation of crime is the particular job at issue in the case before us. We find no evidence that investigation of crime was unique to the sheriffs office at common law. In fact, our supreme court listed the sheriffs investigatory role of "detective" as a duty that is not "novel" to the sheriff but one "so old" that it is "easily forgotten or unappreciated."
Andreski v. Industrial Comm'n,
In the instant case, we note that the drug enforcement program was not unique to the sheriffs office. Deputy Humphreys was assigned to the county's Metro Drug Unit. The unit is a cooperative enforcement program involving the county and municipal police agencies. We see this as additional evidence that the particular assignment did not concern a duty that was unique to the office of sheriff.
Because all the reasons considered above indicate that Deputy Humphreys' assignment did not concern a constitutional duty of the sheriff, we conclude that the assignment was covered by the collective bargaining agreement.
The county also argues that Deputy Humphreys' assignment is not subject to the collective bargaining agreement because it was not a permanent position. However, under the terms of the collective bargaining agreement, all assignments over six months were permanent positions subject to the collective bargaining agreement. The duration of Deputy Humphreys' assignment *920 was six months to three years. Thus, the assignment was covered by the bargaining agreement even if the department had no intention of keeping Deputy Humphreys permanently in that position.
We reverse the judgment of the circuit court and reinstate the arbitration award.
By the Court. — Judgment reversed.
