On Monday Governor Jay Nixon signed legislation putting an immediate end to the scanning and retention of personal documents by the Department of Revenue.
The news comes as a special house panel on privacy is pressuring members of Nixon's inner circle to testify, leading to a court fight over the use of legislative subpoenas.
House Speaker Tim Jones realeased a statement Monday saying the change of policy is evidence of the panel's impact.
Jones said the committee's work is not done. He still wants to know who approved the scanning in the first place and he wants assurances that information already collected and stored is destroyed.
The new law prohibits the department from keeping copies of such documents and requires the ones it already has gathered to be destroyed securely by the end of this year.
Lee's Summit State Senator Will Kraus, who sponsored legislation to end the practice, also released a statement thanking the Department of Revenue.
