What is the legal basis for trying a juvenile as an adult?
<p>I understand that it is generally only done for serious crimes, and I believe the reason is to not have the perpetrator's criminal record simply sealed at a certain age, but what is the legal basis in the United States for this?</p>
<p>If you are not yet a certain age, or have passed an age, you just aren't that age... period.  As a society we are obsessed with arbitrary numerical figures as a cut-off for certain privileges, and enforce them strictly to the extent that a 21 year old cannot be served alcohol at 1:00am on their birthday because presumably it falls under the previous <em>serving day</em>.  And I'm pretty sure that same 20 year old couldn't petition the court to be tried as a 21 year old such that they might be found not guilty of a minor in possession charge happening the day before.</p>
<p>Falsifying your age for any reason (other than a social fib) is normally considered illegal.  Certainly there is an expectation that if provided for official governmental purposes, or when entering into a private party contract where age may be germaine, the information provided will be correct.</p>
<p>So what is the legal basis, logic, reasoning, age cut-off, crime severity, or any other standard that must be met to authorize a court to not recognize the correct natural age of a child and hold them to the standards of an adult?  And does a defendant have any say in the matter such as it being part of a plea deal?</p>
<p>Bonus question:  If declared an adult by the court and then acquitted, does the juvenile retain any adult privileges?  (I suspect not, but again it doesn't pass my personal reasonableness test...)</p>

<h2>Juvenile Proceedings in General</h2>
<p>The question seems to assume that having reduced penalties for offenders below a certain age, or special courts or modes of trial for accused under a specific age is natural and automatic. It is actually a comparatively recent feature of US law, and exists only because statutes have so provided. Such statutes are largely matters of state law, and vary from state to state.</p>
<p>When a judge orders that an accused minor &quot;be tried as an adult&quot;, the judge is not pretending that the minor is actually over the age of majority, nor ignoring the accused's actual age. Rather, the judge is following a procedure authorized in the same law or body of law that authorizes special juvenile procedures in the first place.</p>
<p>Such a finding determines the procedure for dealing with a particular charge or case. It does not make the child a legal adult.</p>
<p>The procedures for making such a determination are generally spelled out in detail in the law of the relevant jurisdiction. The details will vary.</p>
<p>Almost anything <strong>can</strong> be part of a plea deal, and juvenile treatment could in theory be part of such a deal, when the relevant law permits, if the judge approves. I believe that is unusual, however.</p>
<h2>Maryland</h2>
<p>Some crimes are, in specific circumstances, to be handled in adult court. In other cases, there is an option to have a case to adult court, following a hearing, in which the child (or the child's  representative) can present reasons not to move the case.</p>
<p>Specifically:</p>

<h2>Falsifying Age</h2>
<p>The question now asserts:</p>
<blockquote>
<p>Falsifying your age for any reason (other than a social fib)  is normally considered illegal.</p>
</blockquote>
<p>This is by no means generally true. Falsifying age to obtain a benefit not otherwise available, such as a reduced price, is fraud. Also unlawful is falsifying age to purchase age-restricted products, such as alcohol. But except where a specific law creates one, there is no general legal duty to provide one's true age.</p>

<blockquote>
<p>I understand that it is generally only done for serious crimes, and I
believe the reason is to not have the perpetrator's criminal record
simply sealed at a certain age, but what is the legal basis in the
United States for this?</p>
</blockquote>
<p>State statutes regarding juvenile justice decide what the minimum age at which one can be tried for a crime is, and for what offenses and at what ages you can be tried as an adult. @DavidSiegel provides an answer with an example of such a statute.</p>
<blockquote>
<p>Bonus question: If declared an adult by the court and then acquitted,
does the juvenile retain any adult privileges? (I suspect not, but
again it doesn't pass my personal reasonableness test...)</p>
</blockquote>
<p>A juvenile tried as an adult for a criminal offense is not &quot;declared to be an adult&quot;, the juvenile is just subjected to the adult criminal justice process (which isn't always worse in terms of due process) and to adult punishments for that particular criminal offense. No one is pretending that the juvenile is a different age.</p>
<p>It is also not akin to the process of &quot;emancipation&quot; of juveniles who are treated as adults for most purposes rather than being subject to the authority of a parent or guardian, because they are self-supporting.</p>
<p>The defendant is still a juvenile for all other purposes and is still sometimes eligible for juvenile offense treatment in future offenses.</p>
<p>In some cases, even if sentenced to an adult sentence after being convicted as an adult in a public adult trial, the defendant will still serve at least the early years of their sentence in a juvenile detention facility.</p>
<blockquote>
<p>So what is the legal basis, logic, reasoning, age cut-off, crime
severity, or any other standard that must be met to authorize a court
to not recognize the correct natural age of a child and hold them to
the standards of an adult?</p>
</blockquote>
<p>Typically, states reserve the option of trying someone as an adult for the most serious &quot;blue-collar&quot; crimes and for adolescents. (Juveniles who commit &quot;white-collar&quot; crimes are rarely tried as adults.)</p>
<p>One reason for this is that belief that even a less-than-mentally-fully-developed juvenile (usually a teenager) still fully understands that certain serious crimes are wrong, appreciates their severity, and understands that these crimes carry serious punishments.</p>
<p>Another is that the maximum sentence for a crime in the juvenile justice system is usually shorter than for a comparable crime committed by an adult and is usually served entirely in juvenile detention facilities away from adult inmates, which isn't viable for a sentence long enough to be considered by legislators to be sufficient for the severity of the crime.</p>
<p>Put another way, the juvenile justice system is optimized for dealing with misdemeanors and minor felonies and not for dealing with very serious violent crimes.</p>
<blockquote>
<p>And does a defendant have any say in the matter such as it being part
of a plea deal?</p>
</blockquote>
<p>Usually the decision is made in the first instance by a prosecutor bringing charges and it is often subject to judicial review at a hearing to determine if the juvenile should be prosecuted as an adult. It is a factor that can be addressed in early plea bargaining in a case, although usually once a prosecutor wins the right to charge a juvenile as an adult, this isn't rolled back in a plea bargain.</p>
