At the beginning of the meeting, there is a reading of the Legion Constitution, which includes "Clause 6, sub-clause 3 [which] requires that every Legionnaire use language-learning machines to learn any new planetary language."
And later Dream Girl quotes clause 2-B, which reads "No one without a super-power can be a member." And she later quotes sub-clause 11, which reads "Making false charges against any fellow-legionnaire shall be cause for expulsion from the Legion." And later yet she quotes clause 2, sub-clause 4 which forbids subverting a legionnaire doing his or her duty.
Lightning Lass becomes Light Lass.
Again Dream Girl quotes from the Legion Constitution: clause 33-B says "If a Legionnaire becomes physically or mentally unfit to perform his duties, he must remain under observation in the Science Hospital for one year." And later she mentions that clause 81 allows punishment for making false charges against a fellow-Legionnaire.
The column starts with an announcement of the new "Hall of Fame" department, which reprints from time to time the "greatest stories of past eras."
