Philip J. Weiser, Attorney General of the State of Colorado, as chief legal
representative for the State, issues this Formal Opinion pursuant to his authority under
§ 24-31-101(1)(a) & (d), C.R.S. (2025), following a request from the State Treasurer.
QUESTION PRESENTED AND SHORT ANSWER
Question Presented.
(1) Does article XI, section 2 of the Colorado Constitution limit the State from
investing in financial instruments that would make the State a subscriber
to or a shareholder in a corporation, or a joint owner with any person,
company, or corporation, public or private, in or out of the state?
Short Answer.
(1) Yes. Although article XI, section 2 does not directly address the State’s
investment authority, it generally prohibits state ownership of stock in a
corporation, subject to recognized exceptions. Whether an investment in a
particular type of financial instrument other than direct ownership of stock
in a corporation would violate the prohibition requires a fact-specific
analysis that is beyond the scope of this Opinion.
ANALYSIS
Article XI, section 2 of the Colorado Constitution prohibits state ownership of
stock in a corporation. While this prohibition has recognized exceptions, none of
those exceptions apply to the situation described in the question presented.

Formal Opinion No. 26-001
I. Article XI, section 2 prohibits state ownership of stock in a
corporation.
The answer to the question presented hinges on the meaning of the “anti-
ownership clause” of article XI, section 2 of the constitution. Interpreting a Colorado
constitutional provision is guided by a dual-pronged obligation: to prevent an evasion
of the constitution’s legitimate operation and to effectuate the intentions of the
constitution’s framers and the people of the State of Colorado. Markwell v. Cooke,
2021 CO 17, ¶ 33. To determine the framers’ intent, the words are given their
“ordinary and popular meaning.” Id.
The anti-ownership clause provides in relevant part:
Neither the state, nor any county, city, town, township, or
school district shall . . . become a subscriber to, or
shareholder in any corporation or company or a joint owner
with any person, company, or corporation, public or
private, in or out of the state. . . .
COLO. CONST. art. XI, § 2. This text is unambiguous: the State may not become a
subscriber, shareholder, or joint owner of a corporation. Id. As relevant here, a
“shareholder” is “one that holds or owns a share in property; especially: stockholder.”
Shareholder, MERRIAM-WEBSTER DICTIONARY, https://www.merriam-webster.com/
dictionary/shareholder. Plainly, the State is prohibited from directly owning stock in
a corporation.1
Consistent with this plain meaning, the Colorado Supreme Court has
summarily observed that this provision “prohibits state ownership of corporate
stock.” Se. Colo. Water Conservancy Dist. v. Fort Lyon Canal Co., 720 P.2d 133, 142
(Colo. 1986). In Southeastern, the Colorado Supreme Court analyzed whether the
State was prohibited by article XI, section 2 from purchasing stock in a mutual ditch
company. Id. at 136. In doing so, the Colorado Supreme Court noted the long line of
Colorado cases holding that mutual ditch companies (i) are not “true” corporations in
a legal sense but merely vehicles for individual ownership of water rights, (ii) are
incorporated and operated under different statutory provisions than corporations,
1 While the question presented uses the term “financial instruments,” that term is not part of the
constitutional text. Instead, article XI, section 2 addresses situations where the State becomes a
subscriber, shareholder, or joint owner of a company or corporation. Modern financial markets
provide a broad range of financial instruments with their own terms and conditions, each of which
would need to be analyzed on its own merits to determine if it falls within the constitutional
prohibition. Given that variety, this Opinion addresses only the direct ownership of stock in a
corporation, which is most clearly within article XI, section 2’s scope.

and (iii) receive different constitutional and statutory protections. Based on these
considerations, the Court concluded that stock ownership in a mutual ditch company
constituted ownership of a real property interest (which did not violate the
constitutional prohibition), rather than a personal property interest in stock. Id. at
141–42.
This interpretation aligns with the framers’ intent. “The provision was
originally enacted to prevent state ownership of, and financial support for, new
railroads within the state.” Id. at 141 (citing Colo. Cent. R.R. Co. v. Lea, 5 Colo. 192
(1879)); accord McNichols v. City & Cnty. of Denver, 74 P.2d 99, 106 (Colo. 1937)
(“Section 2 prohibits the state from becoming a joint owner with any private person
or corporation.” (citation omitted)); cf. State v. Nw. Mut. Ins. Co., 340 P.2d 200, 201
(Ariz. 1959) (interpreting nearly identical provision in the Arizona Constitution
adopted for the same reason and remarking that “the evil to be avoided was the
depletion of the public treasury or inflation of public debt by engagement in non-
public enterprises”).
That article XI, section 2 prohibits stock ownership in a corporation by the
State is bolstered by persuasive authority from other jurisdictions with analogous
constitutional provisions. Those courts largely conclude that, unless the ban against
the State being a shareholder or stockholder is textually limited to ownership that
aids the corporation, such ownership is plainly prohibited. Compare State ex rel.
Gainer v. W. Va. Bd. of Invests., 459 S.E.2d 531, 533–34 (W. Va. 1995) & Sprague v.
Straub, 451 P.2d 49, 52–55 (Or. 1969), with Almond v. Day, 91 S.E.2d 660, 667–68
(Va. 1956). To this end, several states with provisions nearly identical to Colorado’s
have since amended their constitutions to expressly permit state investments in
corporate stock. See ARIZ. CONST. art. IX, § 7; see also MONT. CONST. art. VIII, § 13.
Taken together, by its plain text, article XI, section 2 prohibits the State from
directly owning stock in a corporation.
II. The recognized exceptions to article XI, section 2 do not apply to
the purchase of stock in a corporation when motivated by the
State’s voluntary investment decisions.
The constitutional prohibition, however, is not absolute. Baked into article XI,
section 2 itself are two enumerated exceptions for state ownership of a corporation or
company:
• if the ownership accrues “to the state by escheat, or by forfeiture, by operation
or provision of law”; or
Page 4
Formal Opinion No. 26-001
• if the ownership accrues to the state “by forfeiture or sale of real estate for
nonpayment of taxes, or by donation or devise for public use, or by
purchase . . . under execution in cases of fines, penalties, or forfeiture of
recognizance, breach of condition of official bond, or of bond to secure public
moneys, or the performance of any contract in which . . . [the state] may be
jointly or severally interested.”2
The question presented, however, appears to assume that the State would
voluntarily engage in investments resulting in State ownership of stock in a
corporation. Neither exception would apply to that situation.
CONCLUSION
Article XI, section 2 does not expressly address the State’s investment
authority. But, by its plain text and as interpreted by the Colorado Supreme Court,
it generally prohibits the State from directly owning stock in a corporation. Further,
none of the recognized exceptions to that prohibition would apply to the
circumstances at issue in the question presented.
Issued this 13th day of April, 2026.

2 The Colorado Supreme Court has recognized a public purpose exception to other prohibitions
contained in article XI, section 2. In re Interrogatory Propounded by Governor Roy Romer on House
Bill 91S-1005, 814 P.2d 875, 882–83 (Colo. 1991) (regarding the public purpose exception to the anti-
donation clause in article XI, section 2); City of Aurora v. Pub. Util. Comm’n., 785 P.2d 1280, 1289
(Colo. 1990). Colorado appellate courts have yet to consider whether that exception similarly applies
to the anti-ownership provision at issue here, and it remains an open question.
