well, you can, at least in 8.1.4  

When I came here I found up to 10 not null constraints on the same columns.  

Got them all off and found some again.... seemed the other choke ... dba.... didn't understand that not null was a check constraints and for some reason kept putting them on ... I think via Toad (I never get a straight answer from him) Then we I showed him on some new tables he created all the dups, instead of deleted them, he disabled them all.....  

gotta love it. if there is a way in Oracle someone can use and abuse it!

Well, you can't have two "not null" constraints on a column (see example below showing the error) as far as I know.
