Legal text appendix

Citations alone aren't enough. A claim that "the Pennsylvania uniformity clause prevents progressive municipal taxation" is a useful claim, but a reader can't really evaluate it without seeing what the uniformity clause actually says, where it lives in the state constitution, and how courts have interpreted it. The legal text appendix is where the actual law gets reproduced (or linked, when reproducing is impractical) and organized.

The aim is navigability of the legal chain, not exhaustiveness. We're not trying to be a law library. We're trying to make sure that any claim made in a domain analysis can be traced back to its source by a reader who wants to verify it — without that reader having to know how to navigate the U.S. Code, the Pennsylvania Statutes, or the Philadelphia Code from a cold start.

For quick definitions of acronyms and terms-of-art (rational-relationship requirement, Schedule SP, HUP test, QOZ, FICA, etc.), see the glossary. The glossary gives a one-paragraph definition; this appendix gives the full legal-chain treatment with statutory text, citations, and case law.

What goes in each per-domain appendix

For each statutory or regulatory reference cited in a domain analysis:

  • Citation in the standard form for that jurisdiction (e.g., "26 U.S.C. § 32" for federal tax code; "53 P.S. § 6924.101" for the Local Tax Enabling Act).
  • A direct link to the authoritative source — the Office of the Law Revision Counsel for federal code, the Pennsylvania General Assembly site for state statutes, the Philadelphia Code online for municipal law.
  • A short plain-language summary of what the section actually does. One or two sentences. Not legal advice — just orientation.
  • The sub-domain(s) where this section is cited.
  • Notable case law or administrative interpretation, where relevant. Brief.

Why this matters

The two most common ways political analysis goes wrong are (a) citing a law that doesn't say what the writer claims it says, and (b) citing a law that's been superseded, amended, or judicially reinterpreted. Both are reduced — not eliminated, but reduced — by making the underlying texts easy to reach. A reader who can pull up the actual statute in two clicks is more likely to catch errors and challenge claims; an analytical project that knows it'll be checked is more careful.
