Abstract This chapter considers the “equity will not” doctrines, such as “equity will not enjoin a crime,” “equity will not protect personal rights,” “equity will not punish,” and “equity will not protect political rights.” It analyzes the formal structure of these doctrines (which is rule-exception). It also analyzes the two functions of these doctrines, namely their regulation of access to equity and their aid in preserving equity’s legitimacy. This chapter also briefly considers the “equity will not” doctrines’ current status, suggesting that most are still in use today, and concludes by arguing that they have enduring functions, even if their traditional scope may need to be adjusted.
