<h1>Detention and linguistic profiling of migrant workers sparks legal challenge and political mobilisation ahead of polls.</h1> Detention and alleged profiling of Bengali-speaking migrant labourers in several non-Bengal states has prompted the Bengal government to explore legal options against what it calls 'unconstitutional deportation.' Incidents include detentions, utility cut-offs, and alleged pushbacks without prior citizenship verification, with some individuals later repatriated after citizenship was confirmed through legal and diplomatic intervention. The primary legal tensions concern citizenship verification, the procedural adequacy of detentions, and the legality of cross-border repatriations framed as linguistic profiling and criminalisation of poverty.
