LOKEN, Circuit Judge.

       Since 1913, Missouri has required public utilities conducting business in the
State to receive prior approval from the Missouri Public Service Commission before
purchasing stocks or bonds issued by another utility. See MO. REV. STAT.
§ 393.190.2. In this case, Southern Union Company applied to the Commission for
blanket approval to make non-controlling investments in utilities that do not operate

       The HONORABLE ANDREW W. BOGUE, United States District Judge for
the District of South Dakota, sitting by designation.
in Missouri. Following an evidentiary hearing, the Commission denied the
application, concluding that it may not grant blanket approvals, and alternatively that
the approval sought would be detrimental to the public interest. Southern Union then
filed this action against the Commission and individual Commissioners under 42
U.S.C. § 1983, seeking a declaratory judgment that § 393.190.2 violates the
Commerce Clause and impermissibly conflicts with federal statutes. The district
court1 granted summary judgment in favor of defendants, concluding the Missouri
statute does not violate the Commerce Clause and is not preempted by federal law.
Southern Union appeals, challenging only the district court’s Commerce Clause
ruling. Reviewing that decision de novo, we affirm.

                                   I. Background.

       Southern Union is a Delaware corporation having its principal office in Austin,
Texas. Through its Missouri Gas Energy division, Southern Union provides natural
gas service to over 480,000 customers in central and western Missouri. Southern
Union is subject to the Commission’s regulatory authority, see MO. REV. STAT.
§§ 393.110 to 393.295, including the requirement in § 393.190.2 that a regulated gas
corporation must obtain the Commission’s prior approval before acquiring the
securities of another utility, whether or not the other utility operates in Missouri.

       Southern Union filed the application at issue in April 1998. The application
stated that Southern Union “has had the goal of selected growth and expansion within
the utilities industry, including by acquiring other energy distribution or transmission
businesses,” that “very few states have a provision as restrictive as” § 393.190.2, and
that “an acquisitive company . . . like Southern Union . . . must be able to make
investment decisions quickly, and in some instances, quietly.” Southern Union
requested a five-year blanket approval to make investments in utility companies that

        The HONORABLE NANETTE K. LAUGHREY, United States District Judge
for the Western District of Missouri.
                                      -2-
do not operate in Missouri, provided the investments do not exceed in the aggregate
$50,000,000 and would not cause Southern Union to hold more than ten percent of
the voting securities of another utility. Southern Union promised to maintain records
of all such transactions and to provide the Commission with copies of any filings with
other regulatory agencies, such as the federal Securities and Exchange Commission.
Following a hearing, the Commission denied the application in August 1999. The
Commission first determined that it does not have authority to grant blanket
approvals, that is, it may not permit Southern Union “to enter into stock acquisitions
in which the time, the target, the price, and the financing terms are all unknown.” The
Commission then determined that the requested blanket approval was not in the
public interest because “even with subsequent rate case review, a significant potential
exists that Missouri ratepayers could be harmed” by investment losses.

       Southern Union then commenced this action, alleging that § 393.190.2 as
interpreted by the Commission violates the Commerce Clause and is preempted by
the federal securities laws or by the Public Utility Holding Company Act of 1935, 15
U.S.C. §§ 79 to 79z-6. In addition, invoking the district court’s supplemental
jurisdiction, Southern Union alleged that the Commission’s denial was unlawful and
unreasonable under Missouri law. See MO. REV. STAT. § 386.510 (authorizing
judicial review of Commission decisions). In March 2001, the district court granted
summary judgment rejecting Southern Union’s federal claims. Southern Union Co.
v. Missouri Pub. Serv. Comm’n, 

, 1206-10 (W.D. Mo. 2001).
Two months later, the court issued an order abstaining from deciding the state law
claim and remanding that claim to state court. This appeal followed.

      With this appeal pending, the state trial court ruled on remand that the
Commission may issue the requested blanket approval, and that Southern Union’s
application was unreasonably and unlawfully denied on the merits. However, on
March 22, 2002, the court granted the Commission’s motion to vacate that judgment
and dismissed Southern Union’s petition for review. Before this court, the

                                         -3-
Commission continues to assert that its pre-approval authority is constitutional. The
order denying Southern Union’s application has not been overturned by the state
courts. Thus, the issue before this court -- whether § 393.190.2 as applied is valid
under the Commerce Clause -- is not moot.2

                                    II. Discussion.

        The Commerce Clause of the United States Constitution authorizes Congress
“[t]o regulate Commerce . . . among the several States.” Art. I, § 8, cl. 3. In addition,
“[t]he negative or dormant implication of the Commerce Clause prohibits state
taxation or regulation that discriminates against or unduly burdens interstate
commerce and thereby impedes free private trade in the national marketplace.”
General Motors Corp. v. Tracy, 

, 287 (1997) (citations and quotation
omitted). As the district court explained, “the scrutiny to which a State statute is
subject depends on whether its impact on interstate commerce is direct and substantial
and is designed to obtain an economic advantage for the State at the expense of its
sister 

. Accordingly, “regulations designed to further
economic protectionism” are presumptively invalid. Middle South Energy, Inc. v.


      2
         Effective July 1, 2001, the Missouri Legislature amended the State’s Business
Corporations Act to provide that “no foreign corporation doing business in this state
shall be required to obtain prior approval of any state agency to acquire . . . the stock
or bonds of another foreign corporation . . . which does not conduct business in this
state.” MO. REV. STAT. § 351.608. The plain language of this new statute seems to
grant Southern Union, a foreign corporation doing business in Missouri, the right to
invest in foreign utilities without seeking the Commission’s prior approval.
However, on remand from the district court, the state trial court ruled, in the order
it later vacated, that § 351.608 “does not apply to the Commission.” The court did
not explain its ruling, and this issue of state law remains unresolved. The issue was
not raised in the district court and has not been briefed or argued on appeal.
Whatever the meaning of the new statute, it does not render our case moot because
the Commission’s order denying Southern Union’s application for blanket approval
remains in effect.

Arkansas Pub. Serv. Comm’n, 

, 416 (8th Cir. 1985). On the other hand,
when a statute “regulates evenhandedly to effectuate a legitimate local public interest,
and its effects on interstate commerce are only incidental, it will be upheld unless the
burden imposed on such commerce is clearly excessive in relation to the putative
local benefits.” Pike v. Bruce Church, Inc., 

, 142 (1970).

      Southern Union argues that § 393.190.2 violates the Commerce Clause by
regulating interstate stock transactions that occur entirely outside Missouri. Using
terminology from some of the Supreme Court’s Commerce Clause opinions, Southern
Union asserts that § 393.190.2 is per se invalid because it is both “extraterritorial”
and “direct” regulation of interstate commerce. Southern Union cites no authority
supporting this contention in the context of public utility regulation. If § 393.190.2
were so obviously unconstitutional, it is startling , to say the least, that the statute has
gone unchallenged for nearly one hundred years.

        Southern Union’s argument ignores this nation’s long history of public utility
regulation. For over fifty years, Congress has regulated the interstate transmission
of natural gas (the Natural Gas Act), the interstate transmission of electric power (the
Federal Power Act), and the ownership of utilities (the Public Utility Holding
Company Act of 1935). A major purpose of these laws was to preserve and protect
state and local regulation of the distribution of natural gas and electricity to local
retail customers. See, e.g., General Motors v. 

; Panhandle
Eastern Pipe Line Co. v. Public Serv. Comm’n of Ind., 

, 517-24 (1947).

       The statute here at issue is part of Chapter 393 of the Missouri Statutes, which
authorizes the Commission to establish “just and reasonable” rates for the local
distribution of natural gas, electricity, water, and sewer services. Rate regulation is
a complex process. A public utility’s investments in other companies can affect its
regulated rate of return, if investment losses are allocated to the regulated business.
Transactions between affiliated utilities can present rate regulators with difficult

                                            -5-
issues of preferential treatment and cost allocation. The abuses Congress identified
in enacting the Public Utility Holding Company Act attest to the long-standing
regulatory concern over interlocking ownership and management of public utilities.
See North Am. Co. v. SEC, 

, 701-02 & n.11 (1946). This concern does
not mean that Southern Union’s acquisition strategy is necessarily contrary to the
public interest, but it tends to confirm the presumptive validity of Missouri regulating
that strategy by requiring pre-acquisition approval.

       The Commission asserts that § 393.190.2 is part of its rate regulation
responsibilities. Southern Union does not deny that assertion, and the administrative
record in this proceeding supports it. For this reason, Southern Union’s contention
that this is merely “extraterritorial” regulation of interstate commerce is incorrect.
Though Southern Union’s stock purchases are no doubt conducted from its corporate
headquarters in Texas, the Commission scrutinizes these transactions because they
potentially affect the company’s regulated rate of return in Missouri. Thus,
§ 393.190.2 regulates interstate stock purchases because of their impact on Southern
Union’s regulated local activities in Missouri. Likewise, calling this “direct”
regulation of interstate commerce does not make it per se unlawful. As the Fourth
Circuit observed in Baltimore Gas & Elec. Co. v. Heintz, 

, 1421 (4th
Cir. 1985), the direct/indirect distinction is not analytically helpful when a state
statute regulates interstate stock transactions for the purpose of protecting local
consumers from public utility abuses.

       In its recent Commerce Clause decisions, the Supreme Court has limited its per
se rule of invalidity “to provisions that patently discriminate against interstate trade.”
Associated Indus. of Mo. v. Lohman, 

, 647 (1994). “The central
rationale for the rule against discrimination is to prohibit state or municipal laws
whose object is local economic protectionism, laws that would excite those jealousies
and retaliatory measures the Constitution was designed to prevent.” C & A Carbone,
Inc. v. Town of Clarkston, 

, 390 (1994); see United Waste Sys. of Iowa,

                                           -6-
Inc. v. Wilson, 

, 767 (8th Cir. 1999). Here, no discrimination against
interstate commerce, or other form of “economic protectionism,” is at work, as it was
in the Commerce Clause cases upon which Southern Union primarily relies -- Healy
v. The Beer Inst., Inc., 

, 340-41 (1989), Brown-Forman Distillers Corp.
v. New York State Liquor Auth., 

, 579-80 (1986), New England Power
Co. v. New Hampshire, 

, 338-39 (1982), and Middle 

. All regulated utilities doing business in Missouri are subject to the prior
approval requirements of § 393.190.2, and Commission approval is required for
purchases of stock issued by Missouri utilities as well as by out-of-state utilities. This
is regulation of a local public utility for the protection of local Missouri ratepayers.
For these reasons, we reject Southern Union’s theories of per se invalidity.

        Southern Union next argues that § 393.190.2 violates the Commerce Clause
under the Pike balancing test. That test requires balancing a legitimate local public
interest against its incidental burden on interstate commerce. On the issue of
Missouri’s public interest, the Supreme Court has stated that “the regulation of
utilities is one of the most important of the functions traditionally associated with the
police power of the States.” Arkansas Elec. Coop. v. Arkansas Pub. Serv. Comm’n,

, 377 (1983). If anything, Missouri’s interest in assuring a reliable and
affordable supply of natural gas for its citizens is stronger than a State’s interest in
regulating the corporate governance of its domestic corporations, an interest that was
sufficient to uphold the Indiana Control Shares Acquisition Act against a Commerce
Clause challenge in CTS Corp. v. Dynamics Corp. of Am., 

, 94 (1987).
Moreover, the long history of utility rate regulation in this country establishes that
Missouri has a legitimate interest in protecting local ratepayers by regulating the
corporate structure of utility companies. See Baltimore 

.

      When we turn to the second part of the Pike balancing test, the burden
§ 393.190.2 places on interstate commerce, we are hampered by the non-specific
nature of Southern Union’s application for blanket approval. Southern Union

                                           -7-
generally asserts that it takes time and money to obtain prior Commission approval,
which is no doubt true. But its further assertion that “Defendants block interstate
transactions by refusing to authorize Southern Union’s investments in non-Missouri
Utilities” is not supported, either by the denial of a specific investment in this case,
or by a review of prior decisions showing that the Commission regularly frustrates
non-control investments in non-Missouri utilities. While we are not certain the
district court accurately described the burden on interstate commerce as “minimal,”
we cannot conclude on this record that it is substantial.

       Similarly, when we come to apply the Pike balancing test, we are hampered by
the non-specific nature of the Commission’s decision in this case. Its rationale for
denying Southern Union’s blanket approval application on the merits -- stock
purchases may result in investment losses -- might be too general to justify a ruling
that severely crippled a specific interstate securities transaction with no showing that
the ruling was essential to effective rate regulation. Cf. Edgar v. MITE Corp, 

, 643-46 (1982). But as Southern Union presented no specific transaction
for approval, the Commission had no occasion to explain in greater detail how its
prior approval authority complements its regulation of utility rates. Thus, the bare
record before us precludes the kind of detailed analysis the Supreme Court requires
before invalidating a state law under the Commerce Clause.

        Section 393.190.2 is part of a complex regime for the regulation of public
utilities in Missouri. Recognizing that local public utility rate regulation is
presumptively valid, and that the Supreme Court has rarely invoked Pike balancing




                                          -8-
to invalidate state regulation under the Commerce Clause, we conclude that Southern
Union has failed to meet its substantial burden to prove that the denial of its blanket
approval application resulted in an unconstitutional burden on interstate commerce.

      The judgment of the district court is affirmed.
