As a novice consumer representative you can use your inexperience to your advantage. No one expects you to know everything. Use the opportunity to ask questions such as:
- would you mind defining that term for me?
- I don't know the background to that decision - could you fill me in briefly?
- why didn't that plan work?
- what was the original intention?
Don't be afraid to ask questions, chances are other members of the committee may also need clarification on issues or additional information.
