## Overview

This one-pager compresses the highest-yield Constitutional Law frameworks into a single review surface you can revisit before mixed sets, essays, or a last-pass memory run.

## Standing

Injury (concrete, particularized) + Causation + Redressability. Taxpayer standing: Only Establishment Clause + Congressional spending. On the exam, treat this as a checklist heading: state the governing rule first, name the trigger or element that matters, and then tie the facts to each part before moving to the next doctrine.

On the exam, treat this as a checklist heading: state the governing rule first, name the trigger or element that matters, and then tie the facts to each part before moving to the next doctrine.
