The Phoenix Sinclair inquiry was halted last month after lawyers representing child and family services agencies demanded full transcripts of interviews done with witnesses.
The Manitoba Court of Appeal rejected the request earlier this month, clearing the way for the hearing to resume.
The lawyer leading the inquiry, Sherri Walsh, says hearings will run from November through to next March.
Had the court allowed the child and family services authorities to access the transcripts, it could have resulted in months of delays.
The inquiry, which began in early September in Winnipeg, had been looking at circumstances surrounding the little girl's death in 2005 on the Fisher River First Nation.
Five-year-old Phoenix was beaten to death by her mother and mother's boyfriend, months after child welfare workers removed her from a foster home and gave her back to her family.
While the girl was killed in June 2005, it was not until nine months later that her body was found, wrapped in plastic, in an unmarked shallow grave near the community's landfill.
The inquiry was established to look at how the province's child and family services officials handled Phoenix's case and why her death went undiscovered for months.
