I will only let you use this answer if you put your system clock
back to today. :-) Furthermore, I don't guarantee it's correct, but
I think it accomplishes what you want to achieve:
delete from dockets d1 where not exists
(select forcode from dockets d2 where d1.forcode = d2.forcode and
d1.comp = d2.comp and d2.docketdate > '31/03/2001')
