Parker's promoter David Higgins claimed the absence of a neutral referee contravened the fight contract.
However, Smith says on this occasion they don't feel the need to deviate from their standard policy.
"We asked them to supply us their names for the other two. They supplied us two other names, which didn't include a New Zealander. When that was questioned, we said we are very happy for a New Zealand judge, absolutely right, got no problem with that at all. But we still haven't had any New Zealand judge sent to us from the WBO for approval. That's ultimately their responsibility.
"As far as we're concerned, we've had a bit of correspondence from Parker's team. We have heard nothing from the actual promoter in this country, Mick Hennessey, but we certainly had something from Parker's team, giving us their thoughts.
"We take on board what their thoughts are, we don't agree. We feel on this occasion, there is no need to deviate from our standard policy."
