Acquittal
In acquitting the Chamberlains in 1988, the Supreme Court found that the alleged "baby blood" found in the Chamberlain's car, upon which the prosecution so heavily relied, could have been any substance, but was likely that of a sound deadening compound from a manufacturing overspray (which contained no blood). This finding underscored inconsistencies in the earlier blood testing, which, along with the later-recovered matinee jacket from a dingo lair area, had given rise to the Morling Royal Commission's doubts about the propriety of her conviction. The court also noted that as DNA testing was not advanced in the early 1980s, the expert testimony given by the prosecution at trial and relied on by the jurors was reasonable evidence at the time, even though it was ultimately found to be faulty.
