I do not think there is any provisions under the Industrial Disputes Act to ask for compensation for legal expenses and/ or penalty from the employer in Labour Court.
Just because you have won a case and had to spend legal expenses for conducting the case, does not automatically entitle you to compensation/ damages unless you can prove that the applicant initiated the case against you with malafide intentions.
Since it is a labour matter, I assume that the said matter was referred to the court after failure of settlement by the labour commissioner. The labour commissioner failed to settle the matter only after the labour considering the dispute as an industrial dispute and hence the matter was referred to court. Now when the labour commissioner considered that there was an existing industrial dispute and referred the matter to court, how the applicant was to be blamed, even if the company wins. This is my thinking.
