I often find introducing enums adds clarity. Here I imagine each enum is an issue which can be resolved through a number of processes:

enum Issue {
  A {
    void handleIt () {
      statement_1();
      statement_3();
    }
  },
  B {
    void handleIt () {
      statement_2();
      statement_3();
    }
  },
  C {
    void handleIt () {
      // Do nothing.
    }
  },
  D {
    void handleIt () {
      A.handleIt();
      B.handleIt();
    }
  };

  abstract void handleIt();
}

Note here that you get the added benefit of being able to handle certain issues using the solutions of other issues (see my D enum).
