The British had named the ground after Maratha warrior king Shivaji in 1927.
"Shivaji Park is named after Maratha warrior king Chhatrapati Shivaji Maharaj. Chhatrapati Shivaji is considered as a deity by eleven crore people in the state," the statement said.
The MPCC said accepting Shiv Sena's demand to change the nomenclature tantamount to change the historical facts in favour of Thackeray family.
Late Shiv Sena chief Bal Thackeray often used to address the ground located at Dadar in Central Mumbai as 'Shiv Tirth' during his rallies.
Shivaji Park is embroiled in controversy over the issue of makeshift structure of late Sena patriarch. While Shiv Sena appears opposing tooth and nail razing the temporary structure, the state government has directed the civic body to remove the "Samadhi" as Shiv Sena prefers to call the structure.
