Question is not worded very clearly. It sounds like the questioner was released for one charge, but is still being detained for a new, or different, charge. If that is the correct scenario, then he is being held legally. The original offense may have been disposed of, but he is NOW being held on a warrant issued for a new and completley different charge. He will be presented in court and arraigned on the new charge in due course. If the "hold" for extradition goes longer than 90 days file a writ of Habeus Corpus. Answer: Actually, the accused must be arraigned within 72 hours or released unless this right was waived. The only charge under US law for which there is no time limit for pre-arraignment detention is Terrorism.
Depending on the charge specified in the warrant: A Justice of The Peace - a Magistrate or - a Judge.
No, a warrant is not the same as a charge. A warrant means the authorities have enough evidence to indicate that further investigation is required or that it is reasonable that charges can be made. A warrant for arrest indicates that there is apparently enough evidence to bring charges and a judge agrees.
Until you appear before the issuing judge
The question is much too general to be answered with any specific answer. There is no information given on the typoe of warrant or what it's for. Usually once a warrant is issued only a judge can release you.
A warrant is issued by a judge, and the judge decides what is necessary.
A writ of habeau corpus is issued to determine such, and the judge must release the person if he/she is being held for no cause.
No, a police officer cannot issue a warrant for your arrest only a judge or court magistrate can do that.
A judge must sign a warrant for it to be active!
A bench warrant is a bench warrant whether it is issued by a criminal court judge or a civil court judge.
A JUDICIAL Officer must review the affidavit for legal sufficiency - once they sign it it becomes valid. A judicial officer would include a Judge, Justice Of The Peace, or a Magistrate.
The date must be there on a search warrant, issued by a judge.
A warrant is sworn out because you failed to go before the judge at the correct time. This shows contempt for the judge. Going before hom for the offense fulfills the warrant.
