With STD rates dropping and telephone calls become cheap, The idea mooted by Karira is useful and beneficial to all.
Why not appellant give a contact no and request AA to call to get his/r personal hearing over phone?
Though the video conferencing would be best.
The good news of today is that BSNL has dropped STD rates to Rs. 1.20 per minute. So, the applicant can even request the AA, that he himself will call the AA at the appointed time and participate in the hearing and thus pay for the call. Even if the hearing is 30 minutes - total cost is only Rs. 36.00. Very small compared to the time, effort and money needed to even attend a First Appeal hearing even locally in one's local town, leave alone to travel to another town.
In any case, most mobile phones these days have a "speaker phone" facility.
