Texas: Standing
<blockquote>
<p>Citizens can sue abortion providers for alleged violations, and
plaintiffs will receive $10,000 from the accused if successful. The
law also impacts anyone who &quot;aids or abets&quot; an abortion, which could
potentially include a driver who unknowingly drove a woman to an
abortion clinic.</p>

<p>If the source is correct, what is there a general rule of thumb or reasoning that determines who can / can not litigate for said $10K in a Texas court room?   Is there Federal law that governs who has standing?  or is it solely at the discretion of TX law?  I am trying to understand: with respect to standing, is this a state decision or does national law somehow trump state law.</p>

<p>Standing requirements are different in state and federal courts, and from one state to the next. A random individual would not have standing to object to a stranger's abortion in federal court, and likely not in any state court, under normal circumstances, as they are not injured in any meaningful way by the abortion.</p>
<p>I don't know what the normal rules of standing are in Texas, but it is likely perfectly acceptable for the Legislature to wave its wand to grant standing to whomever it wants regarding any violation of the law it sees for. That seems to be what is happening here.</p>

<p>The other answers are right to point out that standing is largely determined by state law.</p>
<p>Texas in particular has a strong precedent for this sort of law. For example, <em>Spence v. Fletchler</em> in the Texas supreme court concerned a similar law allowing private citizens to sue &quot;bawdyhouses.&quot; The opinion was clear that &quot;such citizen shall not be required to show that he is personally injured by the acts complained of.&quot;</p>
<p><a href="https://static.texastribune.org/media/files/122f5ddf767d6417d964738f1ec2f6cc/Hughes%20-%20SB8.pdf" rel="nofollow noreferrer">This has been reaffirmed many times, and as recently as 2019</a>.</p>

<h2>The legislature has the power to grant or limit standing</h2>
<p>The common law on standing in each state is different depending on how the doctrine that a party must have sufficient connection to and harm from the law or action challenged to support that party's participation in the case has played out in each state.</p>
<p>Notwithstanding, the legislature has the power to grant or limit standing as it chooses.</p>

<p>There is one caveat at federal level; one qui tam law <a href="https://en.wikipedia.org/wiki/Qui_tam#False_patent_marking" rel="nofollow noreferrer">was</a> judged unconstitutional, because it completely removed the state from the equation in a criminal matter:</p>
<blockquote>
<p>In 2011, the United States District Court for the Northern District of Ohio held that the False Marking Statute was unconstitutional. Judge Dan Aaron Polster determined that it violated the Take Care Clause of Article II of the Constitution, because it represented &quot;a wholesale delegation of criminal law enforcement power to private entities with no control exercised by the Department of Justice&quot;.</p>
<p>[Subsequently] The America Invents Act made significant changes to false marking laws, that affected all pending and future false marking actions:</p>
<p>Only the U.S. government can now sue for the civil penalty authorized in § 292 [...]</p>
</blockquote>
<p>The better known False Claims Act <a href="https://en.wikipedia.org/wiki/False_Claims_Act#Provisions" rel="nofollow noreferrer">procedure</a> mandates that the government actually be (first) notified of the lawsuit and not the actual defendant.</p>
<p>So there are some constitutionally derived limits how far standing can be extended to random parties, at least in some matters.</p>

<p>Traditional standing requirements in federal courts, are doctrinally derived from Article III of the U.S. Constitution which governs the federal judicial power.</p>
<p>State constitutions or state common law have been invoked to apply substantially identical standing requirements in state court in most kinds of cases, but sometimes with narrow exceptions for advisory opinions in connection with the legislative process. Under Texas precedent, <a href="https://static.texastribune.org/media/files/122f5ddf767d6417d964738f1ec2f6cc/Hughes%20-%20SB8.pdf" rel="nofollow noreferrer"><em>Spence v. Fletchler</em>, and subsequent Texas cases</a>, even a &quot;bounty&quot; type scheme that allows parties without standing to bring certain kinds of lawsuit, is constitutionally permitted under Texas law.</p>
<p>The U.S. Supreme Court in the case of <em><a href="https://www.supremecourt.gov/opinions/21pdf/21-463_3ebh.pdf" rel="nofollow noreferrer">Whole Women's Health v. Jackson</a></em>, applies a standing test to the federal court challenge of the state law, but the majority opinion is agnostic as to state requirements to show standing or something equivalent that Texas S.B. 8 does not itself require. As some pertinent parts of the Official Syllabus to the opinion explain:</p>
<blockquote>
<p>(3) The petitioners name other defendants (Stephen Carlton, Katherine
Thomas, Allison Benz, and Cecile Young), each of whom is an executive
licensing official who may or must take enforcement actions against
the petitioners if the petitioners violate the terms of Texas’s Health
and Safety Code, including S. B. 8. Eight Members of the Court hold
that sovereign immunity does not bar a pre-enforcement challenge to S.
B. 8 against these defendants. Pp. 11–14.</p>
<p>(4) The sole private defendant, Mr. Dickson, should be dismissed.
Given that the petitioners do not contest Mr. Dickson’s sworn
declarations stating that he has no intention to file an S. B. 8 suit
against them, the petitioners cannot establish “personal injury fairly
traceable to [Mr. Dickson’s] allegedly unlawful conduct.” <em>See
California</em>, 593 U. S., at ___ (slip op, at 9). P. 14.</p>
<p>(c) The Court holds that the petitioners may bring a pre-enforcement
challenge in federal court as one means to test S. B. 8’s compliance
with the Federal Constitution. Other pre-enforcement challenges are
possible too; one such case is ongoing in state court in which the
plaintiffs have raised both federal and state constitutional claims
against S. B. 8. Any individual sued under S. B. 8 may raise state and
federal constitutional arguments in his or her defense without
limitation.</p>
<p>Whatever a state statute may or may not say about a defense,
applicable federal constitutional defenses always stand available when
properly asserted. See U. S. Const., Art. VI. Many federal
constitutional rights are as a practical matter asserted typically as
defenses to state-law claims, not in federal pre-enforcement cases
like this one. <em>See, e.g., Snyder v. Phelps</em>, 562 U. S. 443 (First
Amendment used as a defense to a state tort suit). Other viable
avenues to contest the law’s compliance with the Federal Constitution
also may be possible and the Court does not prejudge the possibility.</p>
</blockquote>
<p>Justice Sotomayor's dissenting opinion in <em>Whole Women's Health</em> argues that if the State delegates unsupervised authority for private individuals to enforce state law in matters in which they have no standing, that it may do so but that this has consequences. She reasons that when a state does this, that the state has effectively hired these private individuals to be state government officials who are bound by injunctions against any state official even if they are not personally involved in the injunction litigation (Slip. Op. at 7-9):</p>
<blockquote>
<p>No party has identified any prior circumstance in which a State has
delegated an enforcement function to the populace, disclaimed official
enforcement authority, and skewed state-court procedures to chill the
exercise of constitutional rights. Because S. B. 8’s architects
designed this scheme to evade Young as historically applied, it is
especially perverse for the Court to shield it from scrutiny based on
its novelty.&lt;3&gt; . . . &lt;4&gt;.</p>
<p>&lt;3&gt;The Court responds by seizing on my mention of S. B. 8’s chilling
effect. Ante, at 16. No one contends, however, that pre-enforcement
review should be available whenever a state law chills the exercise of
a constitutional right. Rather, as this Court explained in Young,
pre-enforcement review is necessary “when the penalties for
disobedience are . . . so enormous” as to have the same effect “as if
the law in terms prohibited the [litigant] from seeking judicial
construction of laws which deeply affect its rights.” 209 U. S., at
147. All the more so here, where the State achieves its unconstitutional aim using novel procedural machinations that the
Court fails to acknowledge.</p>
<p>&lt;4&gt; The Court also holds that the Texas attorney general is not a
proper defendant. For the reasons explained by THE CHIEF JUSTICE,
ante, at 2– 3, this conclusion fails even under the Court’s own logic.
The Court further observes that “no court may ‘lawfully enjoin the
world at large.’” Ante, at 10–11 (quoting <em>Alemite Mfg. Corp. v. Staff</em>,
42 F. 2d 832 (CA2 1930)). But the petitioners do not seek such relief.
<strong>It is Texas that has taken the unprecedented step of delegating its enforcement authority to the world at large without requiring any
pre-existing stake. Under the Court’s precedents, private actors who
take up a State’s mantle “exercise . . . a right or privilege having
its source in state authority” and may “be described in all fairness
as . . . state actor[s].</strong>” <em>Edmonson v. Leesville Concrete Co</em>., 500
U. S. 614, 620 (1991). This Court has not held that state actors who
have actual notice of an injunction may flout its terms, even if it
nominally binds other state officials, and it errs by implying as much
now. The Court responds by downplaying how exceptional Texas’ scheme
is, but it identifies no true analogs in precedent. See ante, at 11
(identifying only “somewhat” analogous statutes). <strong>S. B. 8 is no tort
or private attorneys general statute: It deputizes anyone to sue
without establishing any pre-existing personal stake (i.e., standing)
and then skews procedural rules to favor these plaintiffs.</strong></p>
</blockquote>
<p>This analysis is a twist on the analysis discussed by @Fizz in an answer looking a the standing issue in some <em>qui tam</em> actions as a question of how much authority a legislative body may delegate (in that case, in a federal litigation context).</p>
