UK Athletics chairman Ed Warner remains hopeful World 400m champion Christine Ohuruogu will be granted a reprieve and be allowed to run in the 2008 Olympics.
Ohuruogu marked her return after a year's ban with a Worlds gold
The British Olympic Association handed Ohuruogu a lifetime ban from Olympic selection after she was banned for a year for missing three doping tests.
But Warner told BBC Radio 5live: "I'm very hopeful there are two precedents that stand her in very good stead.
"Let's be really clear, this is a young athlete that has never failed a test."
The BOA has received her appeal, which is supported by UK Athletics, and an independently-chaired appeals panel will hear it in due course.
World triathlon champion Tim Don successfully appealed against a similar ban given for a similar offence, which would suggest Ohuruogu has reason to be optimistic.
And Warner says the 23-year-old, who took gold at the World Championships last week and helped the 4x400m relay team to bronze, has his full backing.
"Amongst all the hurly burly and ill-informed comments in the media this past week, let's not forget she has never ever failed a drugs test," he said, "and she has taken many, many tests in the past year.
"This is an individual case and it needs to be argued on that basis.
"The three-strikes-and-you-miss-a-year rule I agree with entirely. What we need to work on with the testers is making it as easy as possible for honest athletes to be tested - there are a few wrinkles to be ironed out there."
