Plaintiff brought this original action for mandamus to compel the Attorney General to certify to the Insurance Commissioner that the articles of incorporation submitted by plaintiff are in compliance with the Insurance Code. Plaintiff also asks the Court to compel the Insurance Commissioner to issue a certificate authorizing the incorporators to proceed with the organization of Fireman’s Fund Insurance Company of Michigan.
*819The agreed-upon facts can be determined from an examination of the briefs of both parties. On April 9, 1980, plaintiff filed with defendant Insurance Commissioner the articles of incorporation of a proposed insurance company to be called Fireman’s Fund Insurance Company of Michigan (hereinafter Fireman’s), together with the bylaws, the plan of organization and operations, a statement by each incorporator and the stock subscription agreement. The incorporators paid the required fees for the cost of examination, investigation and processing of the application by the commissioner. Plaintiff then submitted additional information. At that point, the application was allegedly in order for review by the Attorney General and Insurance Commissioner.
Fireman’s intended to offer insurance against all hazards and risks, except life, title and mortgage insurance. Fireman’s would be a subsidiary of the American Insurance Company and belong to the Fireman’s Fund Insurance Group, a group of 16 insurance companies owned by the American Express Corporation. Fireman’s would locate its home office and principal place of. business in Southfield, where an associated company had previously located its branch office. Plaintiff then expected Fireman’s to consolidate and take over the transferable insurance business of other Fireman’s Fund companies which have written insurance in Michigan.
On August 22, 1980, the Attorney General issued an opinion holding that the Insurance Commissioner may refuse to accept the articles of incorporation of a proposed domestic insurance company where the purpose of incorporation in Michigan is to avoid the premiums tax imposed upon foreign insurers. A copy of this opinion was *820sent to plaintiff’s attorney. On December 12, 1980, the Insurance Bureau wrote that it was unable to complete its review of plaintiff’s application because the Attorney General had not advised the commissioner of his approval of the articles of incorporation. Plaintiff requested the Attorney General to issue a determination of approval or disapproval without delay. The Attorney General then informed the Insurance Commissioner that he would not approve Fireman’s proposed articles for the reasons expressed in the earlier opinion.
Plaintiff filed a complaint for a writ of mandamus on April 13, 1981. This Court issued an order to show cause on July 22, 1981.
As both parties make clear in their briefs, at stake is the premiums tax liability of a foreign insurer which incorporates a domestic subsidiary through which all of its business in the state is done. Foreign companies doing insurance business in Michigan pay a substantial tax on premiums on all insurance written in Michigan.
I
Plaintiff argues that mandamus is the only remedy available and that plaintiff has been forced to seek a writ of mandamus by defendant’s refusal to follow proper statutory procedures.
This Court has mandamus jurisdiction over state officials under GCR 1963, 714.1(1). An action against a state officer is proper in the Court of Appeals or the circuit court at the option of the party commencing the action. MCL 600.4401; MSA 27A.4401; Schweitzer v Board of Forensic Polygraph Examiners, 77 Mich App 749, 753, fn 5; 259 NW2d 362 (1977), lv den 402 Mich 837 (1977). When there is a plain, direct and adequate alter*821native remedy, courts will not permit the use of a writ of mandamus. Coffin v Detroit Bd of Ed, 114 Mich 342; 72 NW 156 (1897). Mandamus is inappropriate where there is another adequate remedy in law or in equity. Clarke v Hill, 132 Mich 434; 93 NW 1044 (1903). See, also, Oakland County Bd of Road Comm’rs v State Highway Comm, 79 Mich App 505; 261 NW2d 329 (1977), lv den 402 Mich 907 (1978), and the cases cited therein.
As to the Attorney General, plaintiff indicates that the clear legal duty to be performed is contained in MCL 500.5020; MSA 24.15020, which states in part:
"(1) Before such articles of incorporation shall be effective for any purpose the same shall be submitted to the attorney general for his examination, and if found by him to be in compliance with this code he shall so certify to the commissioner.”
If plaintiff is correct in his claim that the articles of incorporation submitted for review are in compliance with the Insurance Code, he is entitled to a writ of mandamus. His entitlement to the writ of mandamus rests on the resolution of issue II. The writ does, however, appear to be an appropriate remedy.
As to the Insurance Commissioner, plaintiff points to MCL 500.5024; MSA 24.15024, as containing the clear legal duty which he seeks to compel the commissioner to perform. Subsection 1 requires persons seeking incorporation of an insurance company to prepare and file in the commissioner’s office, with the certificate of the Attorney General certifying the articles of incorporation annexed thereto, a statement showing in full detail the plan according to which the company *822proposes to transact business and a copy of a prospectus and the proposed advertisements to be used to sell stock. The filing is required to contain several other items of information. Subsection 2 requires the commissioner to examine the statements and documents presented to him and states that he shall have the power to conduct any investigation which he may deem necessary and to hear the incorporators and to examine under oath any persons interested in or connected with the proposed insurance company. If, in the commissioner’s opinion, the sale of capital stock in the proposed insurance company or soliciting of membership therein would work a fraud upon the persons subscribing to such capital stock or membership, the commissioner shall refuse to license the person to proceed in the organization and promotion of the insurance company. Further, MCL 500.5040; MSA 24.15040 requires the commissioner, upon the petition of the incorporators, to cause an examination to be made concerning the capital stock to determine if the requirements concerning the same have been fully complied with. Upon being satisfied that all requirements of the Insurance Code precedent to commencing business have been fully complied with, the commissioner shall deliver to the company a certificate of authority to commence business and issue policies.
It is clear that the duties of the commissioner which plaintiff seeks to compel her to perform may not be performed before the certification of the articles of incorporation by the Attorney General. No clear legal duty has yet devolved upon the commissioner which she has breached. Mandamus ordinarily will not issue unless the defendant is under a clear legal duty to act. Hill v State Highway Comm, 382 Mich 398, 402; 170 NW2d 18 (1969). The Insurance Commissioner will not be *823under a clear legal duty to act unless and until the Attorney General certifies the articles of incorporation. Even then, the commissioner will not be under a duty to grant the relief sought by plaintiff until she has performed her statutory functions, under MCL 500.5024; MSA 24.15024 and MCL 500.5040; MSA 24.15040. The facts presented do not show that the commissioner has failed to perform any legal duty owed to plaintiff, clear or otherwise.
We find that this action in mandamus is an appropriate means of seeking relief against the Attorney General. At the same time, no writ may issue against the commissioner because the facts presented do not show any legal duty on her part at this time.
Defendants also claim that plaintiff has another adequate remedy, i.e., a declaratory judgment action in circuit court. We reject this claim for failure to support it with argument or authority. Plaintiff does not seek merely a declaration of rights but rather a mandate to state officers to perform their legal duties. Plaintiff clearly claims that he is entitled to immediate action on the part of defendants.
II
Although we have determined that mandamus is an appropriate remedy ajgainst the Attorney General, it remains to be decided whether the facts of this case warrant the issuance of a writ. This depends on whether the Attorney General properly refused to certify the articles of incorporation. We believe he did hot and that certification of the articles should have been granted. It appears that the discretionary determination that has been *824made by the Attorney General is more properly within the province of the Insurance Commissioner.
Before further analysis takes place, some clarification of the role of the Attorney General’s opinion should be made. Plaintiff submitted documents to the commissioner who submitted them for certification of the articles of incorporation by the Attorney General. The Attorney General issued an opinion stating that the Insurance Commissioner, not the Attorney General, could disapprove a filing as a domestic insurer if, after investigation, she found that the purpose for incorporation in Michigan was to avoid the premiums tax imposed upon foreign insurers. OAG 1979-1980, No 5758, p 930 (August 22, 1980). Later, the Attorney General wrote to the commissioner, with a copy to plaintiff, stating that he had disapproved the articles of incorporation for the reasons stated in his opinion. Of course, nothing in the opinion stated that he had such power.
In justifying his refusal to certify plaintiff’s articles of incorporation, the Attorney General relies on MCL 500.5020(1); MSA 24.15020(1), which requires him to certify the articles "if found by him to be in compliance with this code”. MCL 500.5008(2); MSA 24.15008(2) requires that the articles submitted contain:
"* * * Fourth, The purposes of the incorporation and the reference to the chapter of this code under which such purposes are enumerated and under which such company intends to operate * * *.”
The Attorney General suggests that these provisions are the basis for the refusal to certify. Al*825though plaintiff stated the purposes of incorporation, the Attorney General found that such purposes were not in compliance with the Insurance Code.
Plaintiff, on the other hand, argues that the Attorney General’s review of the articles of incorporation is a formal one, intended only to determine whether the application itself complies with the code. Plaintiff argues that, if the Attorney General finds the stated purpose to be an illegal one under the code, it reasonably follows that he may refuse to certify the articles for failure to be "in compliance with this code”.
Very few cases have interpreted the sections concerning the rules for organization of domestic stock and mutual insurers. It appears here, however, that the Attorney General has attempted to usurp the powers of the Insurance Commissioner. MCL 500.5024(2); MSA 24.15024(2) specifically provides that the commissioner shall have the power to conduct any investigation deemed necessary concerning the incorporation of a domestic insurance company.
The Court recognizes the differing treatment accorded domestic and foreign companies by the Insurance Code which may indicate a legislative intent to preclude foreign insurers from establishing shell companies within the state to gain favorable treatment.
The code contains many distinctions between domestic and foreign insurers. Fees are different for domestic insurers and foreign insurers, MCL 500.240; MSA 24.1240. MCL 500.403; MSA 24.1403 requires only foreign insurers to obtain a certificate of authority concerning solvency. Special requirements for possession of assets for foreign insurers are set forth in MCL 500.404; MSA *82624.1404. Special requirements concerning the corporate purposes of foreign insurers are set forth in MCL 500.406; MSA 24.1406. The applicable deposit requirements for domestic insurers differ from those for foreign insurers as set forth in MCL 500.411; MSA 24.1411. Foreign fire, fire and marine and marine and inland insurers must also file an agreement as to competition, which is not a requirement for domestic insurers, MCL 500.422; MSA 24.1422. Foreign insurers are required to file certain documents concerning their admission to do business in the state of their origin or incorporation, MCL 500.424; MSA 24.1424. The rules concerning names for the conduct of business differ, MCL 500.454; MSA 24.1454.
Of particular importance in determining, the Legislature’s intent is the differing tax treatment accorded domestic and foreign companies. MCL 500.440; MSA 24.1440 imposes a premiums tax of two percent or three percent, depending on the type of insurance, on all premiums on business written or renewed in the state. Domestic insurers are subject to the Michigan Single Business Tax Act, MCL 208.1 et seq.; MSA 7.558(1) et seq. The single business tax is similar to a value-added tax in that it taxes what one has added to the economy in contrast to an income tax which taxes what one has derived from the economy. Stockler v Dep’t of Treasury, 75 Mich App 640, 643-644; 255 NW2d 718 (1977), lv den 402 Mich 802 (1977), app dis 435 US 963 (1978). Such a tax is more likely to impose a heavier burden on true domestic insurers than on instrumentalities of foreign insurers incorporated in Michigan because it taxes business activity as a whole.
Also indicative of a possible legislative intent to preclude the type of incorporation plaintiff seeks *827to make is the presence of a retaliatory tax in MCL 500.476; MSA 24.1476. The retaliatory tax imposes a tax upon insurance companies of other states equal to that imposed on Michigan companies doing business in those states where the aggregate tax burden on Michigan companies doing business in those states exceeds the burden on companies of those states doing business in Michigan. Such a tax is rendered ineffectual if companies of those states may form domestic Michigan insurers which do business only in Michigan.
All of the differences in treatment, however, simply do not give authority to the Attorney General to refuse to certify the articles of incorporation. The Attorney General made his decision without granting any opportunity to the incorporators to be heard. Considerations of whether an insurance company seeks to form a sham domestic corporation merely for the purpose of receiving preferential treatment must be made by the Insurance Commissioner after providing some opportunity to the incorporators to be heard. Such serious allegations cannot be properly considered merely by a review of the articles of incorporation and a gut reaction that something suspicious is about to occur.
Upon reaching this conclusion, we determine that the writ of mandamus sought by plaintiff against the Attorney General should now issue. No writ will issue against the Insurance Commissioner because such issuance would be premature, the commissioner never having refused to do her duty. This Court anticipates that further proceedings will be conducted by the Insurance Commissioner as guided by this opinion and that of the Attorney General when, and if, plaintiff requests the Insurance Commissioner to pursue the application.
*828This Court cannot reach a decision on plaintiffs argument that the premiums tax on foreign insurers is unconstitutional. Any decision now would be premature.
A writ of mandamus is granted against the Attorney General.
