Warrants don't expire: once one is issued it can be served or recalled. Until this happens the warrant stays active.
A warrant never expires unless the warrant is served & returned (you're arrested) or a judge revokes the warrant.
Oh, yes.
A warrant is a judicial order for an arrest. If the warrant was still valid, the law enforcement officer has no choice but to make an arrest.
You can get bail only if you have been arrested and arraigned or the judge who issued the arrest warrant set bail when the warrant was issued (however, arrest is still a prerequisite for making bail).
Unless the arrest warrant specifically states that the issuing agency will extradite then you can not be arrested for it.
No. No warrant that has been issued ever expires until it has been served.
yes, a warrant is a warrant.
No, they arresting officers do not have to have the warrant in their possession, only the knowledge that it exists.
A warrant is a command from the court that a specific person be arrested and brought to the court. If the warrant is still active then the officer has little choice, he is probably required by law to arrest you.
Don't understand the question. How can a warrant "expire before it starts?"
Until the judge that issued it withdraws it, or the warrant is served. It never expires.
Yes.
