A bench of Acting Chief Justice Gita Mittal and Justice C Hari Shankar said Maken's assistance could be necessary as he was the Transport Minister in the Sheila Dixit government in Delhi and might be able to provide valuable insight into why environment friendly buses were not procured earlier.
The court allowed an application to be moved on his behalf in a PIL challenging Delhi government's decision to procure more buses for the city to strengthen its public transport system in view of the poor air quality.
Delhi government standing counsel Sanjoy Ghose opposed the intervention on behalf of Maken saying it was a "publicity stunt."
Disagreeing with the contention, the bench asked, "Is there any prohibition that a politician cannot bring or raise a public interest issue before a court?"

"His assistance may be necessary as he was a transport minister and we might get valuable insight into why the buses were not bought then (when Congress was in power)," it said.
Petitioner Nipun Malhotra, who suffers from locomotor disability, has challenged the Delhi government's move to procure 2,000 standard floor buses at a cost of Rs 300 crore, saying these were not equipped for wheelchair access and thus would "directly and substantially affect" about 2.34 lakh disabled persons in the national capital.
The bench had refused to stay the procurement but said there was an urgent need for more buses in the city and the Delhi government needed to address it on a "war-footing".
The PIL is listed for hearing on December 13.
