Disregards (9)
'disregards' is the definition.
('ignore' can be a synonym of 'disregard')
This is all the clue.
(Other definitions for ignores that I've seen before include "Snubs" , "cuts" , "Shrugs off" , "Cold shoulders" , "Intentionally disregards" .)
(Other definitions for overlooks that I've seen before include "misses something" , "Fails or pretends not to notice" , "Superintends" .)
