Yes it is. This is because the government needs answers and if you don't want to justify and you refuse you most likely know something important.
The Fifth amendment to the US constitution.
no because you kill yourself and you cant testify if you are dead
Immunity yeah, if your a narc and testify in court against your co-defendants
Then there would be nobody to testify and the hearing would continue.
Your question is unclear. In the USA, a defendant does NOT HAVE TO testify at his trial, ever. The defendant is the one accused of committing the crime. He does not have to say anything (OJ Simpson did NOT testify in his first trial, Scott Peterson did NOT testify at his trial.) The Prosecutor will present his case (with all his evidence and witnesses) explaining to the jury (or judge) WHY the evidence shows the defendant committed the crime. The Defense Attorney will present his case (with all his evidence and witnesses) explaining to the jury (or judge) WHY the evidence does NOT show the defendant committed the crime. The defendant does not have to be one of those witnesses. He cannot be forced to testify.
Yes. Citizenship is not a pre-qualification to testify in court.
That depends on how it is arranged. You can settle the case out of court with a legal agreement. If the case is going to go on without you, and you are suggesting blackmail or a bribe just so you don't testify or "forget" things during your testimony... that is illegal. I suggest talking to an attorney about what you have in mind.
WHAT court case does he not want to testify in - his own? He has that right if he wishes to exercise it. If you are referring to some other case in which he may not want to testify - the court has the power to compel his attendance and be called as a witness. If he takes the stand and refuses to answer questions or testify, the jury can then draw their own conclusion from his refusal, and use that, or not, in their deliberations.
If you are a qualified expert hired to testify yes. Otherwise no. It is your civic duty to testify if summoned.
If you testify against, you argue against them.. If you testify for then, you agree with them and support them
No, the word 'testify' is not a noun at all.The word 'testify' is a verb: to give evidence as a witness in a law court.The verb to testify is a word for an action: testify, testifies, testifying, testified.The abstract noun forms of the verb to testify are testimony and the gerund, testifying.
Sorry, no, that is not enough, In the US the defendant is entitled to be confronted by their accuser. In a Forcible Robbery case it is a crime against the state and you are the Complaining Witness (Complainant). It is not within your power to "drop charges" or anything like that. Talk it over with the Prosecutor and tell him/her your apprehension.
