His clients are contesting the Wellington City Council's (WCC) refusal to allow their brass band and dancers into community parades – namely the Christmas parade, Cuba Street Carnival, and the Chinese New Year parade.
"[Falun Gong] are a colourful and interesting spectacle. They make no political protest on that parade and they've got as much right as somebody advertising fruit juice," Mr Ellis said.
He said the "religious and spiritual" group have as much right to participate in the parades as the Council itself does, "which is plainly a political organisation".
"It's hypocrisy."
The Wellington City Council issued a directive earlier this year that Falun Gong be excluded from all Council-sponsored events, naming the group "political".
This new policy breaches four major sections of the Bill of Rights Act including Freedom of expression and Freedom from discrimination in New Zealand, according to Mr Ellis.
The statement of claim also alleges that one of the reasons behind the ban is because the Council want to keep friendly with their sister cities in China, Mr Ellis said, calling these actions, "the thin end of the wedge".
"Obviously the Council have an opportunity to defend their position. But whatever their position is, I think the City Council's actions are significantly unlawful."
Richard McLean, spokesperson for the Wellington City Council said the Council will be contesting the claims in court.
"What we're saying is we're not so concerned about whether they're political or not."
The Council were more concerned about "how the event was run", he said.
Mr McLean said he didn't know if there were links between the Chinese Embassy and the organisers of the Chinese New Year parade.
Former Deputy Mayor Alick Shaw, when pressed about the ban, told Falun Gong members in March that the Council wanted to maintain a good relationship with the Chinese Embassy due to sister city relationships with Xiamen and Bejing.
Mr McLean said they have already informed Falun Gong that they will not be part of this year's Christmas parade.
"The fact they're taking legal action against us we don't really want to comment further except to say that we will be contesting it in the High Court," he said.
Falun Gong spokesperson Chris Thomas said Falun Gong is a spiritual practice based on Truthfulness, Compassion and Forbearance.
Falun Gong's applications into the community parades are a chance for the group's brass band and dancers to share these principles with the community, he said.
"It has absolutely no political objectives. It's about improving yourself as an individual."
Mr Thomas said it has exercises similar to T'ai Chi or yoga and is a practice that is spread throughout communities around the world.
He believes some members of the Wellington City Council have a misconception as to what Falun Gong really is – a claim the Council denies.
"We do call for an end to the persecution, which at the moment involves organ theft from living Falun Gong practitioners; the torture, brainwashing, rape, beatings, and killing of practitioners. And we will continue to so while these most severe human rights violation in China continue," said Mr Thomas.
Falun Gong have assured the Council that these issues would not be brought into the community parades.
"We hope the Wellington City Council will be more supportive to our group and stand with us," Mr Thomas said.
