Disabled people are not exempt from challan and as I have heard talk with him first before handing him over your documents especially something which he can hold to do the challan.
Moving on this was totally wrong as you had the permit but again it has been heard if there is a crackdown against tinted glass in city they just dont acknowledge the permit.
You can do 2 thing
Contest the challan as you were not the driver why did he take your id card, as i know they have been ordered to not give challan on id but driving license. if Contested iand if you succeed you will get your money back and get the warden some spanking but he will keep on being an A$$.
Second option is pay the fine and forgot about and in future cases dont hand over things as ID card, driving licence or car papers.. reason with him.
