The Queensland government has slammed the Liberal National Party opposition for going to court to avoid revealing the source of $100,000 worth of political donations it received.

However, the LNP insists it is seeking to clarify a point of law left ambiguous when the government changed political disclosure rules earlier this year.

Electoral Commission Queensland is taking legal action against the LNP to force the party to provide details of 28 donations the party received between January and June 2014.

Deputy Premier Jackie Trad said the LNP had shown a "lack of leadership" over the issue.
