The wife of anti-whaling campaigner Peter Bethune hopes a ban by Sea Shepherd from its future anti-whaling activities helped his case in Japan.
He faces five charges, including trespass and assault.
The Tokyo trial ended on Thursday, but a verdict will not be given until 7 July.
Sharyn Bethune told Morning Report she is not sure if banning him would have helped her husband's case, but hoped it did.
The charges relate to his boarding of a Japanese whaling ship in the Southern Ocean in February.
