iTnews reported yesterday that the registrar, one of four owned by Nicholas Bolton's Australian Style Investments, had won the injunction and could be back in business as early as this morning.
It was understood at the time of yesterday's ruling that more detailed hearings of the case could be months away.
But all could now hinge on a second appearance by both parties before the Victorian Supreme Court this morning in which auDA will allegedly look to have yesterday's ruling overturned.
"Bottle Domain's injunction was successful and the decision was passed to have our accreditation re-instated until the matter can be heard in greater detail," the registrar said in a statement.
"Unfortunately auDA has appealed the ruling and the matter is once again before the Victorian Supreme Court on Friday 17th of April at 10am.
"Further instructions as well as a formal statement will be issued once the outcome of [today's] appeal has been made."
In a previous interview, auDA's chief Chris Disspain hinted the regulator was ready for a legal challenge of its decision to revoke Bottle Domain's accreditation for alleged lack of disclosure of a security breach.
In a statement, the regulator said it was seeking "clarification as to the effect of the Court's orders [yesterday]."
auDA said it "will fully comply with all orders of the Court". It also said it intends to "vigorously defend" its decision to revoke Bottle Domains' accreditation.
"auDA has a duty to the Commonwealth Government and the Australian internet community to administer the .AU Domain Name System in the best interests of the Australian internet community and to preserve the stability and integrity of the .AU Domain Name System," it said.
A full hearing of the case has been set down for Wednesday 22nd April.
Bottle Domains thanked customers for support they had provided since the case began.
