Former Natural Resources minister Bruce Northrup stands by his actions of more than two years ago, in a dispute with Windsor Energy, that have now sparked a lawsuit.

Northrup claimed at that time the company had violated the province's Oil and Natural Gas Act when it conducted seismic tests along Highway One inside Sussex town limits.

His office also laid a complaint about the Calgary-based company to the RCMP.

No charges were ever laid.

Last Friday, the president of Windsor Energy filed a $105-million lawsuit against the New Brunswick government and Northrup, alleging Northrup made false, misleading and defamatory comments that hurt the company.

Northrup had declined to comment on the lawsuit at the time, but told CBC News on Thursday that he was acting to protect the people of New Brunswick.

"I don't have any ill regrets of what I did there in that situation," said Northrup, who is now the Public Safety minister and Solicitor-General.

"Apparently the other side … thinks I did something wrong, but in my mind I can go to bed at the end of the day with a clear head."

Windsor president Khalid Amin has sent internal government documents to the CBC, showing Northrup was told by one of his advisors that the exploration company did not violate the act when it did the work in Sussex.

In his statement of claim, Amin says the negative publicity drove potential investors away from his company.

Amin alleges his inability to raise money led to the loss of the exploration licences.

He says he stands to lose more than $100 million in profits, claiming that's just part of the potential oil and natural gas holdings an independent report says could be in the licence area.

None of the allegations have been proven in court.
