Yes, the Court can do so.
Added; (in the US) It all depends on WHOSE witness is lying. It is pretty much understood that the defendant and their witnesses will not tell the truth. A case will not be dismissed because of this.
If a prosecution witness is caught in a lie, the court must determine just how badly that witnesses's false testimony impacted the case. If their lie damaged the case irrevocably it is more likely the judge will declare a mis-trial rather then simply dismissing the entire case. But... anything is possible.
If the plaintiff lies during a court case, it can damage their credibility and weaken their case. The judge or jury may not believe their testimony, which could result in the case being dismissed or ruled in favor of the defendant. Lying in court is considered perjury and can lead to legal consequences for the plaintiff.
It means that the case is dismissed because the plaintiff did not show up in court.
The civil case was dismissed because the judge ruled that there was insufficient evidence to support the plaintiff's claims.
Not in a criminal case. In such cases the prosecuting attorney represents all of the people of the state and/or country and therefore represents the orignal plaintiff/victim. A civil trial is basically the same, if the plaintiff has legal representation. For example, a credit card company sues for debt owed. It is understood that the CC's legal counsel if the plaintiff by proxy and has the right to "prosecute" the case. If the civil suit has been brought by an individual plaintiff representing themselves, he or she must be present at the time of the trial or the case will be dismissed (generally w/o prejudice). Likewise, if legal counsel does not appear the case will be dismissed.
If the plaintiff lacks standing to bring an action, the court may dismiss the case for lack of jurisdiction. Standing requires the plaintiff to have a personal stake in the outcome of the case. Without standing, the court cannot hear the case.
Plaintiffs do not charge. They file lawsuits. The plaintiff can always file, but if the case is dismissed with prejudice, a new filing cannot be litigated. If a case is dismissed with prejudice, it means res judicata applies, and a new filing would be dismissed because the issues have already been litigated. If the case is dismissed without prejudice, it means that it has been voluntarily dismissed or dismissed for some reason to allow the case to be refiled and re-litigated later.
If the plaintiff does not appear in court, the case may be dismissed or a default judgment may be entered in favor of the defendant. The plaintiff may lose the opportunity to present their case and the court may rule in favor of the defendant by default.
If a plaintiff does not show up, the case may be dismissed. If a defendant does not show up, a default judgment may be entered against them.
If a case is dismissed with prejudice at the defendant's cost, it means that the plaintiff wins the case. The dismissal with prejudice means that the plaintiff cannot bring the case again, and the fact that it is at the defendant's cost indicates that the defendant is responsible for covering any expenses related to the case.
I think this means when the Plaintiff's case is dismissed, meaning the court is not going forward with the charges, and with the costs, means the Plaintiff is responsible for the court costs. Usually this is done when the court feels the case isn't supported by facts, or evidence, or that the case shouldn't have been filed to begin with. Now it has been a while since a worked in the court system, but I think this still holds water.
Dismiss "with leave" means the case is dismissed, but the plaintiff may re-file to (hopefully) fix whatever was incomplete or otherwise lacking in the original filing. Dismiss with leave is contrasted with dismiss on the merits, which means the case is dismissed and the plaintiff may not re-file. Thus the plaintiff has lost the case.
A case may be dismissed for various reasons, including lack of evidence, procedural errors, jurisdictional issues, or if the plaintiff fails to prosecute the case.
