There are plenty of things broken and bent out of shape in the current polity, structure and governance of the Lutheran Church—Missouri Synod; and even more things are wrong with the proposals being offered by the Blue Ribbon Task Force on Synodical Structure and Governance.
However, the number one fatal flaw in LCMS structure and governance, in my opinion, is the inordinate power that the floor committees have over synodical conventions; especially because those floor committees are ultimately hand-picked by the President of the Synod. That critique is not aimed at the current administration, but at the polity itself on principle.
The floor committees control what comes to the Convention for consideration and action; they control the order and priority of that business, and the manner in which it is presented; and they have the significant ability to speak at length to resolutions, to defend and promote them, above and beyond what any of the other delegates are permitted or able to say or do in response.
Personally, I think the power and authority of the floor committees should be curtailed, for one thing, and the process by which overtures from across the Synod are presented as resolutions to the Convention should be handled more objectively and far more equitably than it has been in recent years. Along with those reforms in our synodical polity, I would suggest that the floor committees, instead of being chosen by the President of the Synod, should be elected by the Districts of the Synod, in much the same sort of way that the nominating committee already is.
Without some such changes in the formation and function of the floor committees, I have little confidence that even improvements in the structure and governance will accomplish any good; although, frankly, it doesn't appear that improvements of any sort are presently in the works.
