Is a judge allowed to consider an argument not made by the plaintiff or defendant?

If a judge is ruling on a criminal case wherein he doesn’t believe the prosecution met the burden of proof, but does believe the defendant is guilty based on his own theory, either legal or factual, is he allowed to rule based on that theory? I guess a corollary question would ask if the judge is supposed to determine guilt or innocence, or the validity of the prosecution’s argument.

I’m assuming you are talking about a non-jury trial where he actually delivers the verdict alone.

According to the way I understand procedures, if he as a judge doesn’t believe the prosecution met the burden of proof, then he would have to rule on that basis.

But what if he rules for the prosecution based not on what the presented, but by what he thinks he knows?

I believe the answer is yes that he can, but he opens his verdict up to be challenged by an appeal. Countless civil rights cases were decided by judges who blatantly railroaded people to jail and were eventually overturned. Or not.

IANAL
As the finder of fact they have pretty wide latitude to believe evidence, disregard evidence, decide on the truthfulness of witnesses and all the other things presented to them, but everything still has to be part of the trial.

Basically this. There are elements to the offense that have to be established by evidence presented in court. The prosecution has the burden of proof to establish these elements. The judge’s “theory” of what happened doesn’t really matter. A judge can certain find that the case was proven based on a different theory than argued by the prosecutor, but it would require sufficient evidence to support that theory. I’m trying to come up with an example.

Let’s say a defendant is charged with auto theft. The prosecution relies on the testimony of the owner who says “I did not give him permission to take my car.” The defendant testifies that the owner did give him permission. The judge doesn’t believe the owner’s testimony but convicts anyway based on a section of the statute that says failure to return a borrowed car within a reasonable time is also considered theft, and the fact that the evidence at trial supported that theory of guilt. So, the prosecutor actually presented sufficient evidence to allow a conviction, but argued the case on one theory instead of the one the judge went with.

Yes. A judge can make a determination sua sponte, i.e., on his or her own initiative.

I’m not quite sure I understand the question. Ordinarily, the determination about whether the prosecution met its burden of proof falls to the jury in a criminal trial. In a “bench trial,” the judge acts as the finder of fact. In a bench trial, if the judge is convinced if the defendant’s guilt, he or she will rule in such a way as to find that the prosecution met its burden of proof. If the judge issues an order that explicitly says that “the prosecution didn’t meets its burden of proof about [some element of the crime] but I am convicting the defendant anyway,” the decision will be subject to appeal. On appeal, the appellate court will review the case to determine whether the judge abused his discretion. In this case, when the judge has admitted that the prosecution didn’t meet its burden of proof, the appellate court would have to overrule the verdict because of the trial judge;s abuse of discretion.

For what it’s worth, a judge can essentially overrule a jury’s conviction, sua sponte, by issuing a judgment notwithstanding the guilty verdict (“JNOV”). the judge can do so when, as a matter of law, the judge can conclude that no reasonable jury could have convicted based on the evidence presented. It’s a rare time when a trial court’s judgment to acquit a defendant can be appealed by prosecutors. The opposite isn’t true - the judge cannot enter a JNOV to convict a defendant if the jury voted to acquit. That would violate the defendant’s right to a jury trial (if applicable) and the protection against double jeopardy.

Generally, no. That’s the jury’s job. The judge’s job is to decide matters of law. The jury is supposed to decide matters of fact.

Didn’t this happen that one time Justice Thomas spoke during oral argument?

ETA: It wasn’t during the ruling but Justice Thomas offered a different line of prosecution (or was it defense?)

IANAL either, but I present the following in response to OP’s question:

Amicus curiae, Latin for “friend of the court,” is someone not a party to the case who feels the need to present information and/or insight that has bearing on the case in the form of a brief. The judge, naturally, has discretion on whether to consider the merits of the brief.

I’ll leave it up to the actual lawyers on the board to elaborate on this.

Edit: On re-reading the OP, I’m not sure the above is relevant. But I’m leaving it up anyway, just in case.

Yes, I was speaking of a bench trial. I was trying to avoid an example for fear of tainting a good general question with a bad specific example but how about something like this:

A prosecutor makes the case that the defendant, accused of murder, entered the victim’s house through the front door. The defense makes a compelling argument that the murderer couldn’t have come through the front door for whatever reason. Somewhere in the case it is mentioned that the back door was wide open.

Could the judge say that while the prosecution didn’t meet the burden of proof based on the their theory of the murder, that they are ruling the defendant guilty because he/she believes the defendant could have easily come through the back door?

As I just wrote the above example I was thinking that there is something inherently unfair about the judge convicting on a theory that the defense had no chance to refute. I’ll try to think of a better example but in the meantime what’s your take on that?

Ok so that answers the legal theory part of my question. Thanks. Now what about the
factual theory? Check out my murder example above.

In a criminal bench trial, the court could find that the State failed to prove every element of the charged offense but find the defendant guilty of a lesser-included offense where all its elements were proven.

A lesser-included offense, as the name implies, includes some but not all of the elements of the charged offense. Trespass plus intent to commit a theft or felony on the premises is burglary, so trespass is a lesser-included offense of burglary. Robbery committed with a weapon is armed robbery. Battery with the intent to kill is attempted murder.

So if a defendant was charged with burglary, and the court believed the defendant was on the premises without authority but the State didn’t prove his intent to steal or commit a felony, the court could find the defendant guilty of trespass. Or if a defendant was charged with armed robbery, and the court believed the victim but felt the State didn’t prove the defendant had a gun, the court could find the defendant guilty of robbery. Or if a defendant was charged with attempted murder, and the court believed the defendant intentionally injured the victim but felt the State didn’t prove his intent to kill, the court could find the defendant guilty of battery.

This can happen sua sponte, without either the State or defense asking for it, only in a bench trial. In a jury trial, a defendant gets to choose whether the jury is instructed on a lesser-included offense if one exists.

Nothing to add as a response to the OP, but a recent example of where a judge (basically) acquitted a person (11 years old at the time) convicted of murder. The kid spent seven years in the pokey, then a judge ruled, “Naw, prosecution didn’t have enough to convict,” so now he’s a free man.

Personally, I would have thought that the judge would have just vacated the conviction and ordered a new trial, but, nope. Set him free.

(I think the kid did commit the crime, but it’s pretty irrelevant now.)

The Jordan Brown case.

To better answer the OP :smack: the judge in a bench trial could convict a defendant of a lesser-included offense by only partially believing the State’s witnesses and/or partially believing the defense witnesses if any. In other words, the court could believe the evidence supports a theory that isn’t exactly the same as either the prosecution or defense theory of the case. “I don’t believe the defendant that he was never in the vacant home, but I also don’t believe the landowner that he caught the defendant red-handed prying pipes from the wall. I’ll find trespass instead of burglary as charged.”

Thank you.

Is there a legal definition of “no reasonable jury” as in:

It’s supposed to be limited to the most extreme cases, where there is essentially no evidence supporting a particular argument, even when viewed in the light most favorable to the non-moving party.

It can happen in criminal or civil cases, but is more common in civil. An example in a criminal case might be a prosecution for obstruction of a police officer. The cop might testify that he saw the defendant walking down the street at 2:00 a.m. and asked him to stop and show some identification. The defendant might argue to the court, “even if that’s all true, it’s not a crime and no reasonable jury could find the elements of the offense based on the testimony of the officer.”

I sat on a jury for a murder trial once in which one of the arguments for the plaintiff’s guilt was that they took a roundabout route leaving the crime scene. One of my fellow jurors lived in the area and could easily realize that what the prosecutor was calling a “roundabout route” was actually the most logical route to take given one-way streets and a railway crossing in that neighborhood. We were allowed to submit a question about this in writing to the judge, who took it up with the prosecutor outside of court. She addressed it in court and dropped that particular argument. All this to say: The judge can consider an argument coming from a juror instead of the prosecution or defense.

In your hypothetical, and consistent with Procrustus’s answer, I believe that the judge could still convict. The prosecution has to prove the elements of the crime beyond a reasonable doubt. Which door the defendant came through is not an element of the crime so it wouldn’t matter whether the prosecution established beyond a reasonable doubt that the defendant went through a particular door.

Before that even went to the jury, I would move for a non-suit. Even accepting the officer’s testimony, no crime is made out.

Will depend on the law of the jurisdiction, but in my jurisdiction, trial courts are very reluctant to allow an amicus, and certainly not to lead evidence. Just points of law.
