What's sauce for the goose is sauce for the gander.

Understand the thought

Meaning in plain English

The same standard should apply to people in comparable circumstances. Do not defend a privilege for one person while denying an equivalent treatment to another.

What the words are saying

The goose and gander differ, but the sauce suits both in the proverb’s image. The comparison challenges a double standard, especially when an exception is justified for someone favoured and refused to someone else. It can prompt a group to state the actual reason for a rule and apply it consistently. Comparable circumstances matters: fair treatment may require different arrangements when needs or responsibilities genuinely differ. The saying is not a demand for mechanical sameness. Its useful question is whether a difference in treatment follows a relevant reason or merely preference, power or familiarity.

Everyday example

A committee that allows one member to join remotely accepts the same arrangement for another member with an equivalent scheduling difficulty.

When to use it

Use it when similar cases are receiving different treatment without a relevant explanation.
