Regular and weakly regular bent functions always appear in pairs since their duals are also bent functions. In general this does not apply to non-weaky regular bent functions. However, the first known construction of non-weakly regular bent functions by Ce\\c{s}melio\\u{g}lu et {\\it al.}, 2012, yields bent functions for which the dual is also bent.
