Is it permissible to claim compensation for the freezing of dues and litigation expenses after the court has ruled in my favor?

There is no objection to demanding from the company the litigation expenses and what you incurred to extract your right, because it caused that by its procrastination and refusal to fulfill the right, in accordance with the rule "no harm and no causing harm." However, demanding interest in exchange for delaying the money is not permissible, as that is usury.
