The right not to be treated unfairly is article 14 of the Human Rights Act.
In the law this is called the right to be free from discrimination.
This right means that nobody should be treated worse than others for any reason, such as disability or race. Or for a number of reasons, such as being a young, black, disabled woman.
Staff working in public services can only treat you differently if this is to stop you from being treated worse. For example, providing you with different support so you can access the same things as other people.
When using this right, it has to be joined onto another one of the other rights in the Human Rights Act, such as your right to be safe from serious harm.
For example, think about a person who lives in specialist housing which is paid for by the local council. The local council say they will stop paying for specialist housing because they are different homes that are cheaper. Staff in the local council haven’t spoken to the person or thought about what help he needs.
This issue would be about their right not to be treated unfairly as well as their right to private and family life.
