The House's first order of business every two years (each new Congress) is to adopt a set of rules. This year and next the rules are codified in H. Res. 5, which can be viewed as a .pdf file here:
http://www.rules.house.gov/111/LegText/111_hres_ruleschnge.pdfAs usual, the rules were simply carried over from the last Congress, with 30-some pages of amendments, so it only gets more complicated from there. Interested readers can try to piece together the whole thing by looking here:
http://rules.house.gov/archived_Congresses.aspx?CID=11&GP=2I know that many firms, lobbying, law, and other, spend a lot of time to piece together the whole rules in forms which are easier to read and consult. Perhaps we'll get lucky and one of those folks will wander by.
All of Congress' rules, House and Senate, trace their origins back to 1801, when Thomas Jefferson published his "Manual of Parliamentary Practice for the Use of the Senate of the United States," which was in turn largely borrowed from the rules of procedure which govern the House of Lords.
The text of that treatise can be found here, just under the Constitution:
http://www.gpoaccess.gov/hrm/browse_109.html For what it's worth, here's my ex-professional, unresearched, highly unreliable opinion:
With one outburst, Rep. Wilson committed a number of offenses:
1) He spoke out of turn, which is certainly a violation of the rules of conduct;
2) His allegation, "you lie," was demonstrably false, as the President was referring to a passage of text in the proposed bill he was describing, and therefore...
3) Rep. Wilson falsely impugned the character of a guest of Congress, while speaking out of turn,
while that guest was addressing Congress, and that guest also happened to be an elected official, and that guest also happened to be the President of the United States, which may further compound the offense.
Under the right circumstances (which we won't see), this action could provide justification for unseating Rep. Wilson.
Rep. Grayson's speech, on the other hand, was delivered according to the rules, in proper turn, did not impugn the character of any individual Member of Congress, and cited reports which should prove to be accurate. In other words, he did
nothing that compares to what Rep. Wilson did.
But that's just my opinion, and you shouldn't take my word for it.
