Former deputy chief minister Muzaffar Hussain Baig was among the 24 candidates in Baramulla constituency whose deposits were forfeited.
The ruling National Conference demanded a public apology from opposition Peoples Democratic Party president Mehbooba Mufti over her party's controversial map showing parts of Jammu and Kashmir in China.
Baig is suspected to be associated with some Pakistan-based terrorist organisation and has also undergone training in Pakistan.
