Confirmation

From Robert Hale's report into the Meadow Lake membership sale controversy:

[(T)he local DLC volunteer] readily admitted that he had not contacted the members and had simply filled out the forms based on the information received from the Band offices.

There is no evidence that anyone other than [the local DLC volunteer] handled the applications or arranged delivery to DLC. The applications arrived at DLC campaign office with signatures and volunteers with DLC campaign office did not add signatures. Based on this information the only possible conclusion is that [the local DLC volunteer] entered the signatures on the applications.
...
It is very significant that this scheme did not succeed. One person did try to deceive the party and to abuse the rights of many individuals. But the NDP found out. It was not just one person or one process that revealed this scheme. Questions were raised by all leadership campaigns, by the local executive, by provincial office and by individual members. He tried to deceive the wrong party. He was caught several times over.

The RCMP's conclusions leading to charges against Ernest Morin alone:

"The investigation is complete. There is only one individual who has been charged," Insp. Stewart Kingdon, head of the RCMP commercial crimes unit, told reporters Tuesday at Regina RCMP headquarters.
...
Kingdon said he could not discuss details of the investigation — including whether Lingenfelter was interviewed — because the matter was before the courts.

However, he said he considered the NDP to have been fully co-operative with the investigation.
