As a result, both Campbell and Steele engaged in campaigns of protest to attempt to publicise their cases. Steele escaped from prison several times, to make high-profile demonstrations, including a rooftop protest and supergluing himself to the railings at Buckingham Palace. Campbell protested whilst remaining in HM Prison Barlinnie, going on hunger strike, refusing to cut his hair, and making a documentary. After a lengthy legal argument, the Secretary of State for Scotland referred the case to the appeal court, granting Campbell and Steele interim freedom pending its outcome.
