How to read a cell

A cell is a quotation, not an answer: it says what the authority wrote, which an adviser can cite, and never what you should do. No rate appears unless the page cited carries it. Where an authority publishes nothing on a point the cell says so and names the page read; where a state bars the tax in its constitution rather than publishing guidance on it, the constitution is what gets quoted.
