Opposition Leader Kamla Persad-Bissessar says when her party returns to government there would be a commission of enquiry into the World Gas-To-Liquids (WGTL) project, which cost taxpayers close to $3 billion.
Persad-Bissessar noted that the 1990 insurrection was probed 26 years after it took place.
And that her government also investigated the Clico and Hindu Credit Union failures.
She said there would be an enquiry into the discontinuance of the legal suit with respect to WGTL against former Executive Chairman of Petrotrin, Malcolm Jones.
Persad-Bissessar recommended that the withdrawal of the legal matter be subjected to review by a Joint Select Committee of Parliament.
She said a similar course was taken in England on a controversial matter.
She questioned why a second legal opinion was not sought before the court matter was withdrawn.
Apart from the WGTL matter, she said there was a 561 per cent increase in the cost of constructing the gas optimisation plant.
The initial budget was US $350 million but the eventual cost was US $1.4 billion, Persad-Bissessar said.
