Ask a lawyer and your friend. Grounds to sue mean at least wanting to sue, feeling that an injustice was made, having a legal avenue of suing, and predicting good probability of a favorable outcome. Whether it’s likely he would get a favorable outcome depends on the legal system as well as its components. In case law countries, this might be a strong precedent-setting lawsuit, where the defendant will have an advantage due to the very lack of precedent. In civil law countries, it might be easier as no precedent is needed and discrimination would almost definitely not involve a jury. So if the laws are unbiased, a man and a woman would be treated exactly the same in that case.
