Is it permissible to take money in exchange for expediting a task related to the judiciary?

If what people give you is in exchange for your work as a judge in your job, then it is a forbidden bribe, and its doer is cursed. Your work requires you to stay away from such matters, even if they are in the form of gifts, because their purpose is to help them invalidate a right or establish a falsehood, which exposes you to being expelled from Allah's mercy.
