What is the ruling on working as a human resources accountant in a court that judges by man-made laws, and does this include any cooperation with the court, such as the experts department?

Working in secular institutions and courts is permissible under two conditions: that the field is one in which Islamic law is applied, or involves administrative and organizational procedures that do not entail ruling on matters of property, lives, or sexual relations. And that the worker strives to uphold justice and prevent injustice.

Therefore, the work of an accountant in secular courts is not permissible if the administration rules by secular law or if its rulings are predominantly based on it, because it is an assistance to wrongdoing. It is also not conceivable for the accountant to alleviate injustice, as it is not within their capacity to do so.
