Relatives pushing for a judicial review into hepatitis C deaths from infected blood have asked a court to limit the costs in the event their case fails.
Families want answers over the use of contaminated blood
About 550 patients received contaminated blood in Scotland in the 1970s and 1980s.
Their families believe the full truth has never been properly investigated.
Lawyers for three victims have urged the Court of Session in Edinburgh to limit the liability to £50,000, or they may have to abandon the action.
Scottish Executive ministers have refused to order a public investigation.
This legal action for a judicial review is at a very early stage.
The three families bringing the case had hoped the Health Minister Andy Kerr and Lord Advocate Colin Boyd would agree to the families' expenses being capped at £50,000.
But the minister and Lord Advocate have refused.
The families have stressed they are not asking for any compensation, but said there was a clear public interest in establishing what happened.
They said Scotland was using Hep C contaminated blood some 18 months after England was using a treatment programme which killed the virus.
