I actually like the operations of subcommittees, as someone who sat on other committees where the subcommittee did the work and then hopefully came to an agreement. We normally saved the time of the committee to do committee work other than subcommittee work. I am very positive about a subcommittee approach.
I am also under the assumption that the chair would be there to break ties and would not be voting on subcommittee concepts. What is the practice?
