Dr Frances Kennett, who has been strongly critical of Oxford City Council's move to fortnightly rubbish collection, has failed to win a seat.
She stood as a Conservative candidate in the North area but came second behind Lib Dem Clark Brundin.
Dr Kennett was taken to court by the council after she withheld part of her council tax, claiming that the fortnightly collections had increased the number of rats in the city.
