Gurleen Kaur was among the 3.94 lakh first-time voters in Punjab.
Shiromani Akali Dal chief Sukhbir Singh Badal's younger daughter Gurleen Kaur, a first-time voter, was issued a notice for allegedly violating the model code of conduct.
The show-cause notice was issued for wearing Akali Dal badge when she reached a polling booth to cast her vote in Muktsar, under Bathinda parliamentary constituency, an official said.
The Election Commission took cognizance of videos showing she was wearing the party badge.
"We have issued a notice based on videos and we have issued a notice to her," said Muktsar Deputy Commissioner M K Aravind Kumar.
"After the reply comes, we will decide the next course of action," he said.
In Chandigarh, Punjab's Chief Electoral Officer S Karuna Raju said he was yet to receive a report in this regard.
Meanwhile, Mr Badal posted a picture of his daughter and other family members on his Facebook page after she cast her vote. Gurleen Kaur was among the 3.94 lakh first-time voters in Punjab.
"Today is a great day for us. Gurleen cast her vote for the first time, accompanied by her grandfather Parkash Singh Badal. When the wisdom of age unites with the energy of youth, the country stands tall. It is a proud moment for us and for all those Indians whose children have come of age to be responsible citizens of our noble country," Mr Badal wrote on his Facebook page.
