Baseline response (no ZPI)

The **nine protected characteristics** under the Equality Act 2010 are: 1. **Age** 2. **Disability** 3. **Gender reassignment** 4. **Marriage and civil partnership** 5. **Pregnancy and maternity** 6. **Race** 7. **Religion or belief** 8. **Sex** 9. **Sexual orientation** ### Which ones cannot be justified under any circumstances? Under the Equality Act 2010, **direct discrimination** is generally unlawful and cannot be justified, **except** in very limited circumstances (such as age, where direct discrimination can sometimes be justified if it is a proportionate means of achieving a legitimate aim). However, **direct discrimination** on the following characteristics **cannot be justified under any circumstances**: - **Race** - **Sex** - **Disability** - **Gender reassignment** - **Pregnancy and maternity** - **Sexual orientation** **Direct discrimination** on the grounds of **age** can be justified if it is a proportionate means of achieving a legitimate aim. For **religion or belief** and **marriage and civil partnership**, there are also some exceptions and specific rules. **Summary Table:** | Protected Characteristic | Can direct discrimination ever be justified? | |------------------------------|:--------------------------------------------:| | Age | Yes (in limited circumstances) | | Disability | No | | Gender reassignment | No | | Marriage and civil partnership| No (except for work-related direct discrimination)| | Pregnancy and maternity | No | | Race | No | | Religion or belief | No (with some exceptions) | | Sex | No | | Sexual orientation | No | **In short:** **Direct discrimination** on the grounds of **race, sex, disability, gender reassignment, pregnancy and maternity, and sexual orientation** can **never be justified** under the Equality Act 2010. Only **age** discrimination can sometimes be justified.

Enhanced response (with ZPI)
