9.1 Where the marine safety investigating State(s)
is conducting a marine safety investigation under this Code, nothing
prejudices the right of another substantially interested State to
conduct its own separate marine safety investigation.
9.2 While recognizing that the marine safety investigating
State(s) shall be able to fulfil obligations under this Code, the
marine safety investigating State(s) and any other substantially interested
State conducting a marine safety investigation shall seek to co-ordinate
the timing of their investigations, to avoid conflicting demands upon
witnesses and access to evidence, where possible.
