RAISE_APPLICATION_ERROR works only in exception block

Question

Hi,
I am facing a strange issue. My RAISE_APPLICATION_ERROR wroks only in EXCEPTION block and not in BEGIN block. Please have a look at below description
I have a procedure that has IF Block as shown below.
BEGIN
IF TO_DATE('31-DEC-99', 'DD-MON-RR') > TO_DATE('11-MAR-12', 'DD-MON-RR') THEN
RAISE_APPLICATION_ERROR(-20001, 'some message');
END IF;
END;
-- RAISE_APPLICATION_ERROR is not working in the above code.
BEGIN
IF TO_DATE('31-DEC-99', 'DD-MON-RR') > TO_DATE('11-MAR-12', 'DD-MON-RR') THEN
RAISE EX_ABC
END IF;
EXCEPTION
WHEN EX_ABC THEN
RAISE_APPLICATION_ERROR(-20001, 'some message');
END;
--Here the exception is raised and it works fine.
BACKDROP:
I have made a trigger that does date validations. It calls procedure for all the validations. And the above shown code is a part of the validations that the procedure does.
Please help.

I have myself checked and tested with all these conditions. Tried all to_date formats and dbms_output to be sure of the values but nothing seems to work.
It works in a sample code. But when implemented in the procedure it is ignoring the RAISE_APPLICATION_ERROR.
Condition is correct. Below is the logic because of which I can say it's correct
If 1=1 then
raise_application_error (-20001, 'ABC');
end;
this ignores the raise_application_error.
However if I modify the code with exception block, WITHOUT CHANGING THE CONDITION, iti works fine
if 1=1 then
raise ex_ab
exception
raise_application_error (-20001, 'ABC');
end;
Now the exception is raised.
NOTE: EVen if I am using 1=1 condition in my code, it is still ignoring the RAISE_APPLICATION error but it will raise the same in he exception block.
Not sure how is this possible.Are you saying the below code is giveing different result in your db?
BEGIN
IF 1=1 THEN
RAISE_APPLICATION_ERROR(-20001, 'some message');
END IF;
END;
