These are petitions in this court brought respectively for a writ of mandamus and for a writ of certiorari by the same petitioners against the Attorney General. The petition for a writ of mandamus is reported by the single justice upon the amended petition and upon the respondent’s motion to dismiss and demurrer. The petition for a writ of certiorari is reported by the single justice upon the amended petition and the respondent’s substituted motion to dismiss, demurrer, and return as extended.
The pleadings with the exhibits appended thereto or incorporated therein are voluminous and detailed. The substantive allegations are the same in each petition. For the purposes of this decision it will be sufficient to state them only in the broadest outline.
By indenture dated March 29, 1872, the trustees under the will of James Arnold transferred to the President and Fellows of Harvard College, hereinafter called the College, a fund to be held in trust by the College for the purpose of establishing and maintaining the “Arnold Arboretum” on a large tract of land of the College in West Roxbury (now part of Boston) and for the support of an “Arnold Professor” who should have the care and management of the arboretum. Under this indenture the College became the trustee of a public charitable trust. See
Rotch
v.
Emerson,
The original trust fund has been greatly augmented by subsequent gifts for the purposes of the arboretum, so that its total endowment now amounts at market value to some $5,000,000. It has sent field expeditions to gather specimens in various parts of the world. It now maintains at West Roxbury a collection of some 6,000 species and varieties of living trees and shrubs. It has also at West Roxbury an excellent horticultural-botanical library of about 40,000 books and 15,000 pamphlets and an herbarium of great value containing nearly 700,000 specimens. The conjunction of these resources in one place has given the arboretum a world wide status and reputation as an integrated scientific institution. Members of its staff have been en *248 gaged in full time scientific research, the published results of which have added to the reputation of the arboretum.
The College now proposes to remove to Cambridge the main body of the library and herbarium of the arboretum related to research to be there combined to a greater or less extent with other collections of books and specimens owned by the College in connection with its botany department. There are to be left at West Roxbury only such books and specimens as may be required to provide there “a working library and herbarium.” It is alleged that this proposal, if carried into effect, would break down the arboretum as an integrated scientific institution, prevent future donations for its endowment, and injure its reputation ánd prestige; that it would involve the use of arboretum income for purposes outside the scope of arboretum activities; and that in some respects the intended action would interfere with the independent status of the Arnold Professor as established by the trust indenture. The position of the petitioners is that the College holds the endowment of the arboretum upon an express trust for the benefit of the arboretum alone as an entity separate from the College; that the funds were donated for the benefit of that entity and not of the College; and that the proposed changes, even if beneficial to botany at Harvard in general, would be harmful to the arboretum as a separate institution and would constitute breaches of the trust established by the indenture of 1872.
The petitions contain further allegations that the College has refused to bring a petition for instructions to determine its right to institute the proposed changes and that counsel for the petitioners sought the Attorney General to permit the use of his name in an information to be brought to obtain a declaratory decree. Conferences were had with an assistant attorney general and correspondence took place and arguments and legal opinions were presented with a view to persuading the Attorney General to permit the use of his name. On July 2, 1953, the assistant attorney general rendered a decision in writing in which he states that *249 the judgment of trustees cannot be overridden by the courts unless the trustees decide arbitrarily, capriciously, or in bad faith; that the College reached its decision honestly, faithfully, and for what it considers to be the best interests of the arboretum; that “there is no legal breach of trust”; that “To permit the use of the name of the Attorney General . . . where it is clear to him the trustee is acting in good faith and within the bounds of reasonable judgment and sound discretion, simply because others, equally in good faith, differ with the decision of the trustee, would open the door to unreasonable and vexatious litigations”; and that accordingly by direction of the Attorney General the application was denied.
The petitions go on to allege that the Attorney General has misconceived his duty; that he should have gone no farther than to determine whether there was a question fit for judicial inquiry; and that the decision discloses various specified errors of law and fact.
The petitioners do not allege that they have any right or standing in relation to the subject matter different from that of other members of the public. They do allege that they have for many years been actively interested in the arboretum and have contributed to it, and that all but two of them are members of the visiting committee appointed by the board of overseers of the College to visit the arboretum. So far as appears this committee has no rights or powers, but exists as a part of the machinery of the College merely for purposes of information and advice. It is not alleged that the petitioners are a majority of the committee, or that they are acting in its behalf. Compare
Trustees of Andover Seminary
v.
Visitors,
The prayer of the petition for mandamus is that a writ issue commanding the respondent to vacate his decision refusing the use of his name, to “grant the petitioners a hearing in the proper sense of the term,” and to reconsider the petitioners’ application and grant it if upon full personal consideration of facts and law it appears that the issues which the petitioners seek to raise are fit subjects for judi *250 cial inquiry, even though it may appear to him that the past and proposed action of the College is not in breach of trust.
The prayer in the petition for certiorari is that the writ issue to quash the denial by the respondent of the petitioners’ application for the use of his name, and that the respondent be required to grant a hearing on said application and to decide in accordance with correct principles of law.
In our opinion the decision of the Attorney General not to permit the use of his name in a suit against the College for alleged breach of a public charitable trust was a purely executive decision which is not re viewable in a court of justice. The duty of taking action to protect public charitable trusts and to enforce proper application of their funds rests solely upon the Attorney General as the representative of the public interests. This is so both at common law and under G. L. (Ter. Ed.) c. 12, § 8.

The exclusive character of this duty thus placed upon the highest law officer of the Commonwealth has been repeatedly stated in our decisions. In
Parker
v.
May,
The same principle has been held applicable in other instances where discretion as to taking action is committed to the Attorney General or to a district attorney.
Brierley
v.
Walsh,
By comparing the prayers of the petitions with the extensive argument of the petitioners it appears that they do not make a frontal attack upon the well established principle
*252
that the decision whether he shall act rests with the Attorney General. Instead they attempt a flank attack. They do not claim that they can compel the Attorney General to permit the use of his name. They do not claim that he has refused to act altogether. They admit that he has received arguments both from them and from their opponents. He has exercised his discretion. Their complaint is with respect to the mental processes by which he reached his conclusion, which they contend were such as to lead to an abuse of discretion. See
M. Doyle & Co. Inc.
v.
Commissioner of Public Works of Boston,
We are not convinced that the petitioners, who have no interest other than that of the general public, have any legal right to demand a decision of the court in advance before action is brought, and when action may never be brought, in a matter ultimately resting in the executive discretion of the Attorney General, and when the court in the last analysis can only advise and cannot command. See
Denby
v.
Berry,
The petitioners admit a general lack of authority on the alleged power of the court to make the kind of inquiry which they seek to have the court make in this case. They have cited nothing that appears to us persuasive. In
State
v.
Chisholm,
The petitioners do rely upon cases of two general classes. They cite cases like
French
v.
Jones,
It follows that in each case an order is to be entered sustaining the respondent’s demurrer, and judgment is to be entered dismissing the petition.
So- ordered.
Notes
This section reads, “He [the Attorney General] shall enforce^ the due application of funds given or appropriated to public charities within the commonwealth, and prevent breaches of trust in the administration thereof.” For new legislation establishing a division of public charities in the department of the Attorney General see St. 1954, c. 529.
