Can you justify your decision?
Sign this by asking the person to provide their reasoning. Use the sign for 'justify' with a slight forward lean and raised eyebrows to indicate a yes/no question, or furrowed eyebrows if asking 'how' or 'why' they justify it.

When signing this, use a firm headshake to emphasize the negative. The downward motion of the 'justify' sign can be slightly sharper here to show confidence and boundary-setting.
