Add a additional condition to Case Statement in Switch

Question

Is it possible to add a additional Condition to Switch Statement like below in C#

switch(MyEnum)
{ 
  case 1:
  case 2:
  case 3 && Year > 2012://Additional Condtion Here
       //Do Something here..........
      break; 
  case 4:
  case 5:
       //Do Something here..........
      break;  
 }

In above mentioned example if MyEnum = 3 then it has to be excuted if Year > 2012... Is it possible?

[EDITED]

Year > 2012 is not applicable to case 1 & case 2.
