Welcoming the move, BJP state president Dr Tamilisai Soundararajan said, her portrait can be unveiled in the Assembly on the basis that she was elected six times as the CM of Tamil Nadu.
While the state Congress unit joined in the boycott of the event announced by the DMK - the national party is in an alliance with MK Stalin's DMK - the BJP took a more disapassionate view of the idea.
The DMK, objecting to the big display for a leader it says was steeped in corruption, has petitioned the Madras High court to step in and have the portrait removed. DMK MLA J Anbazhagan had also submitted a representation to Assembly Speaker's office on Sunday against the event, News18 reported.
Tamil Nadu Chief Minister Edappadi Palaniswami had written to Prime Minister Narendra Modi in May past year to be the chief guest for the unveiling.
Jayalalithaa didn't allow Sasikala to stay at her Poes Garden residence out of humanitarian concern but to amass assets and launder her ill-gotten wealth, the court said.
Referring to Jayalalithaa who was the first accused (A1) in the case, the court observed, "However, though in the process of scrutiny of the facts and the law involved and the inextricable nexus of A1 with A2 to A4, reference to her role as well as the evidence pertaining to her had been made, she having expired meanwhile, the appeals, so far as those relate to her, stand abated".
The Assembly Hall has the portraits of all the late Chief Ministers who have served the state, besides Saint poet Tiruvalluvar, Rationalist leader Periyar and architect of Indian Constitution B R Ambedkar.
He had also said that she was regarded as a role model by the chief ministers of other states.
Observing that Ms Jayalalithaa has grabbed the world's attention and has created historyin this historic Assembly, he said he felt as if she was personally blessing the occasion.
