What does the committee bill ensure regarding complaints about members?

The correct answer highlights the importance of independent investigations into complaints about members. This ensures that allegations are examined objectively without bias or influence from those who may be connected to the members being investigated. Independent investigations promote fairness and accountability, as they are conducted by parties who do not have a vested interest in the outcome. This mechanism helps maintain trust in the committee's processes and upholds the integrity of its members by ensuring that all complaints are taken seriously and dealt with appropriately.

In contrast, the other options might not fully capture the essence of the committee's approach. While fair hearings are essential, they do not guarantee the impartiality that independent investigations provide. Regular audits of member conduct can help assess behavior over time but do not specifically address how individual complaints are handled. Lastly, while public disclosure of complaints can promote transparency, it may also lead to reputational risks and deter individuals from coming forward with their grievances if they fear public scrutiny.
