The submission follows a joint meeting held on April 18 under the banner of the Central Young Chakma Association, which was attended by representatives of political parties within the CADC as well as organisations including the Mizoram Chakma Students' Union, Chakma Mahila Samiti, and teachers' and employees' associations.

Participants unanimously termed the erection of the boundary pillar on February 13 as "unwarranted, unauthorised, and highly provocative", warning that such actions could disrupt the long-standing peaceful coexistence between the Lai and Chakma communities.

The organisations reiterated that the boundary between the Chakma Autonomous District Council and the Lai Autonomous District Council (LADC) is clearly defined under the Pawi-Lakher Region (Re-Organisation) Order, 1972. According to the provisions, the boundary runs from the source of the Sanghatuilo Lui stream to its confluence with the Tuichawng Lui.

On this basis, they asserted that villages including Parva-I, Parva-II, Parva-III, Bundukbanga, Gavasury, and Siminesora fall within the jurisdiction of the CADC.

The memorandum urged the Governor to direct the immediate removal of the pillar, citing growing unrest among local residents. It noted that while some residents have expressed willingness to dismantle the structure themselves, elected members from the Parva and Devasora South constituencies have appealed for restraint pending official action.

The organisations cautioned that any delay in resolving the issue could escalate tensions in the region and appealed to the authorities to ensure timely intervention to maintain peace and uphold the rule of law.

Leaders of the CYLA could not be reached for comment.
