Final answer:
Chair's responses during parliamentary inquiries are immune to appeals as they are protected by the principles of freedom of speech within the legislature, enabling individual legislators to raise questions independently.
Step-by-step explanation:
The chair's response to a parliamentary inquiry or any other query is not subject to an appeal because these responses are considered part of parliamentary proceedings which are protected by legislative immunity. This concept, often coded in laws, upholds the freedom of speech within the legislative process. Parliamentary questions are a method for members of the legislature to obtain information from the bureaucracy or to ask questions of ministers without needing the cooperation of other members, thereby serving as a powerful tool for minority parties to raise issues independently.
