Just for ease of reference, I'm reposting the principles as they now stand.

1. The first priority is always given to the latest editions of works published during Tolkien's lifetime.

2. Secondary priority is given to the latest ideas found among Tolkien's unpublished texts and letters, except where they:
a. violate the published canon without specifically correcting an error or
b. are proposed changes that do not clearly indicate the exact details that must be changed and how they are to be changed.

3. If no sources that fall under number 2 can be used to form the actual narrative of a section, then any text or summary created by Christopher Tolkien may be used, provided it does not violate the canon established for that section by numbers 1 and 2 above.

4. No new names and no new expressions in Elvish or in any of J.R.R. Tolkien's special languages may be introduced; all names or expressions in J.R.R. Tolkien's special languages that are updated must be changed either in accordance with a universal change by Tolkien or with a logical reason and a sound etymology.

5. Information in sources of lower level priority is to be preferred over information in sources of higher level priority where the item of information in source of higher level priority can be reasonably demonstrated to be an error, whether a "slip of the pen" or from inadequate checking of previous writing.

6. The actual words used by J.R.R. Tolkien or the editor or summarizer of his work may only be changed, including change by deletion or addition, when:
a) they are minimally changed to agree with statements elsewhere in the canon recognized as of greater validity or are replaced with words or phrases from later or alternate restatements of the same material for reasons of consistancy or are changed to agree with alternate phrasings used by Tolkien of the same or better validity
b) they are minimally changed to avoid great awkwardness of expression such as ungrammatical constructions or too great a difference in style from the passage or section/chapter into which they are now to be inserted.
c) they are minimally added to in order to expand a sentence fragments or an incomplete phrase into a construction that fits grammatically in the new environment
d) they are deleted to avoid redundancy in new passages compiled from more than one source
e) they are, in verse passages, minimal changes that do not add new information to the tale, to maintain the proper metre and rhyme or alliterative pattern of the original verse.

7. Personal aesthetics are not to be used in establishing the actual events in the narrative; all changes and decisions must be justified by the above principles, either:
a) with explicit indication; that is, a text of greater precedence contradicting a text of lesser precedence, or
b) with implicit indication that JRRT almost certainly would have changed/deleted it. But we must base this on some evidence or text from JRRT or CJRT; that is, a text of greater precedence suggesting beyond reasonable doubt a contradiction with a text of lesser precedence, or
c) in cases where two options are given precisely equal validity by the above guidelines, by a majority vote based on personal aesthetics and individual opinions.
A corallary is that we may not disregard any text or note, old idea or projected change, by JRRT unless it is invalidated by one of the above principles, explicitly or implicitly; that is, we must have a REASON for rejecting something.
