Though former chief executive Don Elder apologised to the commerce committee yesterday for some decisions contributing to the company's current predicament, Mr Shearer said he would continue to push for a parliamentary inquiry.
Mr Shearer, in Dunedin yesterday to visit businesses and supporters and to attend the iD fashion show, said the nearly two hours Dr Elder, and former Solid Energy chairman John Palmer, spent before the commerce committee, ''was not enough time to explain why a billion-dollar company was now $390 million [in debt]''.
Solid Energy is carrying at least $389 million debt and has closed mines and cut more than 450 jobs across the country since last August.
It is in talks with its bankers and the Government about a bail-out.
Mr Shearer said issues such as $23 million in bonuses, $130 million in dividends over more than three years, the debt increase by $300 million and management perks during the past decade all required more scrutiny.
''Taxpayers are bearing the brunt of Solid Energy's massive failure - that has to be accounted for,'' Mr Shearer said.
He remains committed to a recent request for a parliamentary inquiry and if necessary would seek to subpoena Dr Elder to explain Solid Energy's management.
While acknowledging a 40%-60% decline in global coal prices was a part of Solid Energy's problem, the Government's urging it to borrow more and pay dividends was untimely.
''It's clear now the debt it took on was disastrous,'' he said.
On the question of Solid Energy now seeking a bail-out, Mr Shearer said he would support, not oppose, such a move to throw the company a financial lifeline because it had ''reasonable mid-term prospects, and many jobs''.
''We don't want to see it sold off in a fire sale ... to be asset-stripped.''
Minister of State-owned Enterprises Tony Ryall said yesterday the troubles with Solid Energy were not due to its debt.
''The problems with Solid Energy come from the fact that the board made a number of investments that didn't generate the returns that they were expecting and together with the most significant collapse in world coal prices a perfect storm has seen this company in the situation that it's in.''
Mr Ryall said the Government took responsibility under the State Owned Enterprises Act.
''The law is very clear. It is the responsibility of the board to manage debt, dividend and investment.''
Mr Ryall said worldwide the financial viability of coal companies had collapsed.
