legal research question
<p>I would like to read civil litigants constitutional challenges.  Where would such filings be filed?</p>

<p>I have read several appeal court and supreme court opinions on constitutional challenges on google scholar BUT where are the actual litigants filings filed?</p>

<p>I have done a PACER search for the cases found on google and the docket for those cases do not show anything that can be construed as a constitutional challenge in that case docket.  I have looked at 3 appeal court dockets which had an opinion on a party's constitutional challenge BUT there is no entry of anything that resembles a constitutional challenge filed in that appeal docket either.</p>

<p>SCOTUS blog has full briefings of cases pending in the U.S. Supreme Court such as <a href="http://www.scotusblog.com/case-files/cases/air-and-liquid-systems-corp-v-devries/" rel="nofollow noreferrer">this one</a>. </p>

<p>PACER has everything filed in every federal case, so I'm not sure why you are having difficulty using that resource.</p>

<p>I suspect that you aren't recognizing what kind of filing a "constitutional challenge" is. This could be located in the body text of a motion (with all sorts of possible titles), a memorandum, a brief, a notice of appeal, a petition (of various types), or a complaint, for example. There is no document entitled "constitutional challenge".</p>

<p>You may want to read a general treatment of the law of civil procedure so that you understand what to look for in a court docket.</p>
