The Samoa District Court will decide this week whether to hold the coronial investigation into the deaths of two babies after being given the MMR vaccine in July.
Talamua Online reports the inquest into the death of the one year olds, was called in the District Court last week.
However, the prosecutor made an application that since the matter is now before the Supreme Court and the nurses are charged with manslaughter, it is appropriate to wait until the case is finished.
The prosecutor also pointed out that police only just received a post-mortem report.
A lawyer for the parents of the babies, Muriel Lui, argued that there were two different matters to be heard in two different courts.
The judge then adjourned the matter until later this week.
