Trudy has formally registered to speak in support of the West Cumbria Mining Project at a public inquiry in September.
The Planning Inspectorate – the Government’s planning regulator – called in the proposals for the mine, which would be built on the former Marchon site in the Kells area of Whitehaven, on March 25.
Statements and comments from interested parties had to be submitted by May 6, with inquiry evidence required by August 10.
The proposal for the mine to produce British metallurgical coal, used specifically to make steel, has received county council planning approval three times.
Last week, Cumbria County Council released a "statement of case" in relation to the mine which revealed it will be taking a neutral stance.
Trudy said: “This decision beggars’ belief. The qualified and highly experienced CCC planning officer has recommended Woodhouse Colliery for approval three times. The democratically elected planning committee has also approved the development, by a majority, three times.
“I hope that the people across Cumbria who value democracy can see through this for what it is - a dictatorial political decision at the very top which goes against all previous decisions.
“I will be speaking at the Inquiry in accordance with the majority view of residents in Copeland, in strong favour of Woodhouse Colliery. Based on the industrial need and mineral availability.”
