It was the Minnesota Pipe Trades Association who just got in banned in
Minnesota. Their argument (Minnesota Plumbing, Heating and Cooling
Contractors and the Minnesota Mechanical Contractors Association) was based
on the controversy that the use of air admittance valves to will provide a
vent terminal inside a building, which is prohibited by the Minnesota
Plumbing Code.
On the other side of the argument was the Minnesota Department of Labor and
Industry Plumbing and Engineering Unit (who had been accepting the method of
venting) and Studor, Incorporated.
Of course they can fail, even vents terminating outside can fail (freeze
over, sealed by snow or birds nest, etc.) But the truth is, they have a
proven track record of not failing, and it's for this reason that they made
it into the new International Codes.
