In a legal dispute, if a respondent has filed their chief evidence, they are generally expected to be available for cross-examination. If a respondent refuses to be cross-examined, the court can infer that their case is not strong or their evidence is unreliable, potentially disregarding it. While their testimony might not be automatically discarded, it will likely carry less weight. It's not mandatory for every respondent to lead evidence, but refusing cross-examination significantly weakens the value of any affidavit or evidence they have submitted.
