Can a person plead the fifth to refuse to acknowledge his identity?
<p>The answer to my earlier question here: <a href="https://law.stackexchange.com/questions/3670/can-you-plead-the-fifth-to-avoid-revealing-the-identity-of-someone-you-were-accu">Can you plead the fifth to avoid revealing the identity of someone you were accused of being?</a> ended up with a side debate I wanted to determine the answer to.</p>

<p>Say that The Green Goblin has been terrorizing Gotham and is accused of many crimes, but no one knows his real identity and thus they do not know who to prosecute.  Eventually Harry Osborn is accused of being the Green Goblin and put on trial.</p>

<p>Can Harry plead the fifth to refuse to admit that he is, in fact, the Goblin?  If "the green goblin" is accused of a crime which was not yet proven can Harry still refuse to admit his identity as the alter ego to avoid being able to be prosecuted for the crime at all?</p>

<p>I had assumed the answer was yes he could, but the above answer seems to imply otherwise...</p>

<p>This is currently untested but the U.S. Supreme Court did leave the door open to allow someone to plead the 5th amendment in order to hide their identity.</p>

<p>In <a href="https://www.law.cornell.edu/supct/html/03-5554.ZO.html" rel="noreferrer">Hiibel v. Nevada</a> the U.S. Supreme Court held that the petitioner did not have a 5th amendment right to withhold his name from a questioning police officer.</p>

<p>The Supreme Court held that Mr. Hiibel could be arrested for failing to identify himself because Nevada's statute requiring identification was narrowly tailored and was not vague. The police officer who stopped Mr. Hiibel had reasonable suspicion that a crime had occurred and Mr. Hiibel could have satisfied Nevada's statute by simply stating his name; there was no requirement to turn over any papers or other documentation.</p>

<p>The final paragraph of the opinion speaks of the importance of the narrow scope of the disclosure requirement and then goes on and states:</p>

<blockquote>
  <p>...Answering a request to disclose a name is likely to be so insignificant in the scheme of things as to be incriminating only in unusual circumstances...Even witnesses who plan to invoke the Fifth Amendment privilege answer when their names are called to take the stand. <strong>Still, a case may arise where there is a substantial allegation that furnishing identity at the time of a stop would have given the police a link in the chain of evidence needed to convict the individual of a separate offense. In that case, the court can then consider whether the privilege applies, and, if the Fifth Amendment has been violated, what remedy must follow. We do not resolve those questions here.</strong></p>
</blockquote>

<p>While the court is leaving unanswered the question of whether there are circumstances where one may refuse to identify themselves, they are making it quite clear that such a situation would be very different than the case decided in Hiibel. There is a strong hint that they would uphold Fifth Amendment privilege in the situation you posit.</p>

<p>I learned in a constitutional law class I took in college that the 5th amendment does not allow you to refuse to give your name to the police. I asked a police officer I used to work with this same question and he told me that if someone refused to give their name to the police that they could be arrested for obstructing justice. <a href="http://www.policechiefmagazine.org/magazine/index.cfm?fuseaction=display_arch&amp;article_id=1150&amp;issue_id=42007" rel="nofollow">According to the Supreme Court, the police may arrest for failure to identify if state law criminalizes such behavior.</a></p>
