OPINION
GRANT, Judge.
The plaintiffs-appellants, Walter and Edwina Franks (Franks), filed a complaint for breach of duty of good faith and fair dealing against the defendant-appellee, United States Fidelity & Guaranty Company (USF & G). USF & G filed a motion to dismiss the complaint for lack of subject matter jurisdiction and for failure to state a claim on which relief could be granted. The trial court granted the motion to dismiss based upon Sandoval v. Salt River Project Agricultural Improvement & Power District, 117 Ariz. 209, 571 P.2d 706 (App.1977). This appeal presents two issues: whether the Arizona superior courts have jurisdiction over and whether there is a cause of action for an injured worker’s claim for damages based upon alleged bad faith administration of a worker’s claim for benefits by his employer’s insurance carrier.
FACTS
Walter Franks was injured on June 19, 1979, while working for Delta Electric, Inc. He qualified for benefits under Arizona’s workers’ compensation laws. The insurance carrier that was to provide the coverage, USF & G, accepted Franks’s claim for benefits.
Franks alleged the following facts in his complaint: The original diagnosis by an orthopedic specialist in June, 1979, was a low back injury in the spinal area. After Franks had undergone conservative medical treatment for about two months he started to have radiation of pain from his back into both legs. On August 13, 1979, he was hospitalized for 18 days. A lumbar myelogram showed evidence of a disc lesion at L-4 and L-5 of the spine.
On April 15, 1980, USF & G had Franks examined by its doctor. On April 23, 1980, USF & G issued a notice of claim status terminating Franks’s compensation and medical benefits retroactively to April 15, 1980, and stating that Franks was in partial temporary disability status as of April 16, 1980.
After a pre-hearing conference USF & G changed its position to claim that Franks had been discharged without permanent disability. On June 4, 1980, USF & G terminated compensation and medical benefits retroactively to April 15,1980. After a hearing in July, 1980, the administrative law judge issued a decision on September 29, 1980, finding that Franks’s condition was not stationary and that he was entitled to further medical treatment and compensation benefits as provided by the workers’ compensation laws.
On October 7, 1980, the insurer gave notice that it wanted another medical examination of Franks by its doctor on October 14, 1980. On October 21, 1980, USF & G issued another notice of claim status stopping compensation and medical benefits as of October 14, 1980, and closed the case without permanent disability. Franks protested the notice and filed a timely request for a hearing. The October 21, 1980, notice stated that compensation was being withheld for the period from April 15,1980, through October 13, 1980, pending receipt of a report indicating Franks’s earnings. Franks gave USF & G a report of earnings in November, 1980, but USF & G failed to pay benefits for the April 15 through October 13, 1980 period.
On March 25 and April 14,1981, hearings were held on the October 14, 1980, termination of benefits. On June 25, 1981, the administrative law judge once again ruled that the condition was not stationary and that Franks was entitled to continued medical treatment and to disability benefits.
In the June 25,1981 Decision Upon Hearing and Findings and Award for Continuing Benefits the administrative law judge found as follows:
