Facts
The care proceedings were heard in two parts, the first part dealing with whether the mother or the father was responsible for the serious physical injuries to the baby which had resulted in the baby's death, and the second part dealing with what should happen to the baby's half-brother. No directions were given that the two parts should be dealt with by a single judge. At the end of the first part, the judge concluded that either the mother or the father was responsible for the death of the baby. The judge did not reserve the case to herself, and the second part was listed in front of a different judge.
