Two possible solutions:

     LabeledStatement:
         Label ':' NoScopeStatement

     Label:
         Identifier
         'case' ExpressionList
         'default'

(replacing CaseStatement and DefaultStatement)
or

     LabeledStatement:
         Identifier ':' NoScopeStatement

     CaseStatement:
         'case' ExpressionList ':' NoScopeStatement

     DefaultStatement:
         'default' ':' NoScopeStatement

_Please_ make up your mind whether it's LabeledStatement or 
LabelledStatement!

BTW the links to CaseStatement and DefaultStatement on statement.html 
are broken.
