Is it legal to prosecute someone for ulterior motives in the US? Suppose someone does something you don't like but isn't illegal. Can you (a prosecutor) prosecute them for something illegal with probable cause not because of their illegal action but because of the legal action you didn't like? Does this fall under abuse of process? Is it against the due process doctrine as the defendant isn't actually being punished for what they're being punished for on paper? Is it at least against a prosecutorial code of conduct? If so, how seriously are such codes of conduct taken? Example: Suppose someone cheated on their wife, can they be prosecuted for the possession of marijuana if the reason that the prosecutor is prosecuting them is the cheating?
Here's some of the law in the area of prosecutorial discretion: In the ordinary case, “so long as the prosecutor has probable cause to believe that the accused committed an offense defined by statute, the decision whether or not to prosecute, and what charge to file or bring before a grand jury, generally rests entirely in his discretion.” Bordenkircher v. Hayes, 434 U.S. 357, 364, 98 S. Ct. 663, 668, 54 L.Ed.2d 604 (1978). Of course, a prosecutor's discretion is “subject to constitutional constraints.” United States v. Batchelder, 442 U.S. 114, 125, 99 S. Ct. 2198, 2204–2205, 60 L.Ed.2d 755 (1979). One of these constraints, imposed by the equal protection component of the Due Process Clause of the Fifth Amendment, Bolling v. Sharpe, 347 U.S. 497, 500, 74 S. Ct. 693, 694–695, 98 L.Ed. 884 (1954), is that the decision whether to prosecute may not be based on “an unjustifiable standard such as race, religion, or other arbitrary classification,” Oyler v. Boles, 368 U.S. 448, 456, 82 S. Ct. 501, 506, 7 L.Ed.2d 446 (1962). A defendant may demonstrate that the administration of a criminal law is “directed so exclusively against a particular class of persons ... with a mind so unequal and oppressive” that the system of prosecution amounts to “a practical denial” of equal protection of the law. Yick Wo v. Hopkins, 118 U.S. 356, 373, 6 S. Ct. 1064, 1073, 30 L.Ed. 220 (1886). In order to dispel the presumption that a prosecutor has not violated equal protection, a criminal defendant must present “clear evidence to the contrary.” Chemical Foundation, supra, at 14–15, 47 S. Ct., at 6. We explained in Wayte why courts are “properly hesitant to examine the decision whether to prosecute.” 470 U.S., at 608, 105 S. Ct., at 1531. Judicial deference to the decisions of these executive officers rests in part on an assessment of the relative competence of prosecutors and courts. “Such factors as the strength of the case, the prosecution's general deterrence value, the Government's enforcement priorities, and the case's relationship to the Government's overall enforcement plan are not readily susceptible to the kind of analysis the courts are competent to undertake.” Id., at 607, 105 S. Ct., at 1530. It also stems from a concern not to unnecessarily impair the performance of a core executive constitutional function. “Examining the basis of a prosecution delays the criminal proceeding, threatens to chill law enforcement by subjecting the prosecutor's motives and decisionmaking to outside inquiry, and may undermine prosecutorial effectiveness by revealing the Government's enforcement policy.” Ibid. United States v. Armstrong, 517 U.S. 456, 464–65 (1996).
I want to file a Federal criminal (not civil) complaint You can't. Only the US government can do that. https://www.uscourts.gov/faqs-filing-case Individuals do not file criminal charges in U.S. district courts. A criminal proceeding is initiated by the government, usually through the U.S. attorney's office in coordination with a law enforcement agency. Allegations of criminal behavior should be brought to local police, the FBI, or other appropriate law enforcement agency. There is an analysis of the relevant law in the case of Smith v. Krieger, No. 09-1503 (10th Cir. 2010). In his second claim, [Smith] sought to prosecute crimes allegedly committed by the defendant judges against the United States. Mr. Smith claimed he had “inherent authority” to raise his first claim under “the Ninth and Tenth Amendments of the United States Constitution.” Id. at 51, ¶ 255. With respect to his second claim, he contended he was “authorized to prosecute crimes committed against the United States by virtue of his inherent authority as co-sovereign, pursuant to powers reserved under the Ninth and Tenth Amendments, and crimes committed against his person and/or property in particular.” [p.13-14] [...] Mr. Smith’s second claim fares no better than his first. Congress has by statute conferred the power to prosecute crimes in the name of the United States on the United States Attorney General and his delegates. See 28 U.S.C. §§ 516, 519. The long-standing view of the Supreme Court is that such power is exclusive. See, e.g., United States v. Nixon, 418 U.S. 683, 693 (1974) (“the Executive Branch has exclusive authority and absolute discretion to decide whether to prosecute a case”) (emphasis added); id. at 694 (“Under the authority of Art. II, [§] 2, Congress has vested in the Attorney General the power to conduct the criminal litigation of the United States Government. 28 U.S.C. [§] 516.”); The Confiscation Cases, 74 U.S. 454, 457 (1868) (“Public prosecutions, until they come before the court to which they are returnable, are within the exclusive direction of the district attorney . . . .”) (emphasis added). Therefore, as the district court concluded, Mr. Smith has no right to initiate a criminal prosecution in the name of the United States under the Ninth or Tenth Amendments, or otherwise. [p.19] Smith was fined $3000 for bringing this frivolous and "abusive" case (which included several other claims besides this one.) Also of note is the 1973 US Supreme Court case Linda R. S. v. Richard D.. Here, Linda R. S. took a slightly different route: in effect, she sought a court order requiring her local district attorney to prosecute Richard D. for a state crime. (Or rather, she sought to enjoin the district attorney from declining to prosecute him.) The Supreme Court ruled: The Court's prior decisions consistently hold that a citizen lacks standing to contest the policies of the prosecuting authority when he himself is neither prosecuted nor threatened with prosecution. See Younger v. Harris, 401 U.S. 37, 42 (1971); Bailey v. Patterson, 369 U.S. 31, 33 (1962); Poe v. Ullman, 367 U.S. 497, 501 (1961). Although these cases arose in a somewhat different context, they demonstrate that, in American jurisprudence at least, a private citizen lacks a judicially cognizable interest in the prosecution or nonprosecution of another.
Can the prosecutor and/or the judge be sued for dereliction of duty, and for non-uniform application of the law? No. Judges and prosecutors have absolute immunity from civil liability for their actions in the course of their duties in connection with the court process. Prosecutors have effectively absolute discretion in their charging decisions and in their decisions to reduce the charges sought against a defendant (prior to jeopardy attaching when a jury is sworn in). Can the outcome of a bench trial be appealed on grounds that the judge did not inform the defendant of his rights Yes. or that his rights were taken away by unwarranted modification of the charges? No. Incidentally, there is no federal constitutional right to a jury trial in a case where six months or less of incarceration is sought as a penalty, and there is no federal constitutional right to counsel unless incarceration is a possible penalty. The Utah State Constitution distinguishes between criminal matters and non-criminal matters in several respects mostly found in the state's bill of Rights (Article I of the State Constitution) in Sections 8, 10, 12, 13, and 19. But, it is fundamentally the right of the state through its prosecutors to decide what charges to press against someone, and they are well within their rights to change their minds. Often, this will be in your favor because reducing an offense to a civil infraction rather than a misdemeanor will have far fewer collateral consequences related to having a criminal record.
Maybe I'm reading Walsh wrong, but it seems to me to be saying that Stout might apply in some cases, but it doesn't in that specific case. I think you are indeed reading it wrong. In the Walsh case, the court says: We have not had occasion to decide the question up to this time, but now that it is presented, we not only reiterate the doubt which we expressed in the McAlpin case (supra), but we think that the question of the defendant's negligence was erroneously submitted to the jury in the Stout case, and that we ought not to follow it as a precedent. It's clearly repudiating Stout here, and not just as it applies to that case. It literally says they think it should not be followed as precedent.
A district attorney has discretion to decide whether to prosecute. A district attorney may be appointed by e.g. a county board of commissioners, or they may be elected. The electorate has the exclusive power to chastise DA, but voting him out of office, so there is little to be done other than write letters to the editor. An appointed DA has some superior, so you can complain to that superior. There is no way to legally force a DA to prosecute if they do not believe that there is enough evidence to get a conviction.
This is called solicitation. A person is guilty of solicitation to commit a crime if with the purpose of promoting or facilitating its commission he commands, encourages or requests another person to engage in specific conduct which would constitute such crime. Model Penal Code § 5.02.
The US legal system deals with this by punishing you for the crimes of which you are convicted. That is, those where the evidence (whatever it is) convinces a jury that you are guilty beyond reasonable doubt. If there is insufficient evidence, for whatever reason then you would not be convicted. The prosecution can, subject to admissibility, put forward whatever evidence they like in order to convince the jury. This can include a pile of ash that they allege contained convincing and unambiguous evidence of guilt. Of course, if that's all they've got the prosecution would probably be censured by the judge for wasting everybody's time and money, more likely, a prosecutor wouldn't lay charges in the first place. As to punishment for an evidence tampering conviction: you have been convicted of evidence tampering, not drug production so you will be punished for evidence tampering, not drug production. The legislature sets different punishments for these for a reason, possibly a reason known only to them but a reason nevertheless. The judge has discretion to apply anything between the minimum and maximum sentence prescribed. A conviction for evidence tampering in a drug case rather than, say, a jaywalking case, is likely to get a more severe sentence all else being equal.
"Double jeopardy" applies to a criminal proceeding, that is one that needs to be proved "beyond a reasonable doubt," and involves criminal sanctions such as jail time. Once OJ was acquitted of criminal charges, he couldn't be tried again as a "criminal." The second trial was a civil trial, with a "lesser" standard of proof (preponderance of evidence), and lesser "damages" (money, not jail time). So even though the facts were the same, OJ was accused of violating a different standard, that is a different "law" so to speak. He could be tried for a "tort" just not a crime. Or put another way, "wrongful death" is not the same as murder. The latter requires intent. Wrongful death suggests "tortious" negligence, but not necessarily intent.
