If you know that the switch statement will only ever have a strict defined set of labels or values, just do this to cover the bases, that way you will always get valid outcome.. Just put the default over the label that would programmatically/logically be the best handler for other values.

switch(ResponseValue) { default case No: return false; case Yes; return true; }
