The Seawall Aksa Didn't Need Twice

Aksa Beach has been through this argument before. In 2022 the Maharashtra Maritime Board (MMB) set out to build a concrete promenade and sea-wall along the shore, and by the time a tribunal finished ruling on it, the sea had already started proving the objectors right.

What MMB built, and where it sits

In July 2022, MMB deployed a team of JCB machines onto Aksa Beach. The machines excavated sand, leveled the shore, and concretized a wide span of it. The finished structure was a concrete road and promenade roughly 600 metres long and 4 metres wide, bordered by a cement sea-wall and boulders, presented by the board as a "sea front development and beautification" project.

Petitioners who later challenged the project argued that Aksa Beach sits within CRZ-I, the most restrictive tier of India's Coastal Regulation Zone framework, a category reserved for ecologically sensitive shoreline, and that this classification matters for a concrete reason, not just a bureaucratic one: the beach acts as a natural barrier against flooding during the monsoon. Concretizing it does not just change how it looks. It changes how it behaves in a storm.

The permission MMB already had, and its limits

The legal foundation for the project traced back to March 2019, when the Maharashtra Coastal Zone Management Authority (MCZMA) issued a CRZ clearance for work at Aksa. That clearance came with an explicit condition: no permanent, solid construction. It is worth sitting with how specific that condition was. The MCZMA was not silent on what could be built here. It had already said, in writing, that whatever went up should not be permanent or solid.

It had also already said no once before, on a related question. Six years prior to the 2023 dispute, the MCZMA had rejected a proposed sea wall at Aksa outright. It had separately rejected proposals for a restaurant, a food plaza, and a gym on the beach. The pattern was consistent: repeated requests to put permanent commercial or defensive infrastructure on this stretch of coast, and repeated rejections, right up until the 2019 clearance that allowed some work under a no-permanent-construction condition.

The challenge

In early May 2023, green activists filed a petition with the National Green Tribunal's western zonal bench. The petitioners, identified as Zoru Bhathena and Banda Nagraj Kumar, argued that the MMB's beautification project at Aksa was illegal construction that violated CRZ rules, and that it exceeded what the 2019 clearance had actually permitted. Their case rested on two linked claims: that the entire beach falls within CRZ-I, and that a solid, permanent promenade and sea-wall is exactly the kind of construction the 2019 order had ruled out.

MMB's defense did not dispute that Aksa is ecologically sensitive shoreline. Instead, it argued the sensitivity cut the other way. The board presented reports from the Central Water and Power Research Station (CWPRS) and IIT Bombay describing Aksa as an eroding site, and argued that an anti-sea-erosion bund was necessary specifically to protect existing infrastructure, including electric poles, from that erosion. In this framing, the wall was not new development competing with nature. It was a defensive structure responding to a problem that was already there.

Activists offered a competing explanation for the project's urgency, one that had nothing to do with erosion control. Aksa Beach sits close to Madh Island, home to celebrities and wealthy businessmen, and critics suggested a real-estate motive behind the push to beautify a public beach in that neighborhood. They also flagged a separate, non-legal risk: Malad, the municipal ward that contains Aksa, is the most densely populated ward in the entire Brihanmumbai Municipal Corporation. Whatever gets built or fails on this coastline affects an unusually large number of people packed into a small area.

Built anyway, while the case was open

The tribunal did not move quickly, and MMB did not wait for it. Activists alleged that by the time of the hearings, the board had pushed the project to nearly 95 percent completion, even as the case was still being argued at the NGT's western zonal bench. Construction and litigation ran in parallel for more than two years: the petition was filed in May 2023, and a final ruling did not arrive until September 2025.

The sea did not wait either. By July 2024, with the tribunal still hearing the matter, the 600-metre seawall had begun caving in, roughly two years after MMB first broke ground on it in July 2022. A structure built and defended as protection against coastal erosion was failing to withstand the coast it was meant to protect, before a single court had ruled on whether it should have been built.

The ruling, and what it actually says

On 17 September 2025, the National Green Tribunal held that the MMB's promenade at Aksa Beach was illegal. The tribunal's reasoning traced directly back to the March 2019 clearance: that clearance had barred permanent, solid construction, and the promenade the board built was exactly that. The ruling did not need to adjudicate the erosion-versus-development argument on its merits. It only needed to establish that MMB had built something the 2019 permission did not allow.

By the time that ruling came down, the practical question of whether the seawall would survive contact with the Arabian Sea had already been partly answered by the seawall itself. It was caving in more than a year before the tribunal decided it was also illegal.

Why this is Aksa's environmental story, not just its legal one

Set side by side, the sequence reads less like a single bad decision than like a system working as designed, just not the design anyone would defend out loud. A coastal authority with a documented history of rejecting permanent structures on this exact beach, including a sea wall six years earlier, granted conditional permission for limited work in 2019. A different arm of the same government then built a permanent structure anyway, defended it with commissioned engineering reports, kept building while a tribunal deliberated on its legality, and produced a structure that began failing on its own terms before the tribunal finished its job. The MCZMA's caution in 2019, and its flat refusal six years before that, both turned out to be warranted. Neither stopped the wall from going up.
