Although these two interpretation are equivalent if the "If. then" and the "Provided, That" are interpreted as expressing single conditionals, they me different when the "If. then" is in-kqwtd as expr.sesing .s bieanditiand far m.+ s biemditianal interpretation the A) and B) alternatives lead to different results when the taxpayer is a citizen and has not earned $10,000 for any satisfactory notion of what is expressed by a single condi-tional (and while it is inappropriate to attempt here to specify just what constitutes such a satisfactory single condition, it should be indicated that the "material implication" of standard twc-vdued propositional logic is clearly unsatisfactory).

Terms appearing in all capital letters are deibed terms. One of the most-needed reforms in careful legal drafting is a reliable way of signding that a term is being used in a defined sense. Using all capital letters is one convenient and relatively unobtrusive way to so signal. The definitions for the terms in all capitals in this article can be found in Alleu and Saxon, "Analysis of the Logical Structure of Legal Rules by a Modernized and formalized Vemion of HoMeld's l%ndamentd Legal Conception.

In interpreting this -Xive instance of "shall" Alternative C) doea not differ from Alternative A) in the results that occur from these interpret atiom in given situatiom. However, the &oice made on this within-sentence ambiguity interects with the dioice made on the between- sentence ambiguity and afkct.s what the negative imtance of "shall" of Alternative B) of the in-terpretation of "If.. then" means and the results that occur horn that interpretation in the same situatiom.

The process of norrndir,in the expression of a set of legal rules, which includes specifying questions about their structural interpretation as well as specifying the constituent sentences for the normalized veruiom of all their structural interpretations, is set forth in detail in the references given in footnote 3 above.
