There are responsibilities that fall under the PU and responsibilities that fall under the CC. Quoting the rule book is no good as it is fraught with errors and inconsistencies. This is another example of this. UIC in the rule book means PU at times and CC at times. Generally it is CC. Although the CC cannot overturn another umpires ruling, he is the final say when it comes to rules interps, weather situations, and the like. PU and BU are equals. If there are 2 umpires, one should be recognized as the CC and it need not necessarily be the PU.
The term UIC is commonly used during a tournament environment where there is one umpire that oversees the umpiring crews. Although that is the case, there is still a CC on the field.
Simply discussing terminolgy I know but there are differences.
