Cairn was awarded damages of over $1.2 billion plus interest and costs in a long drawn-out tussle over a tax dispute and the Indian government is now liable to make this payment. An Indian official, however, said at the time the government would likely challenge the order.

If India does not comply with the order it would be a violation of international rules on arbitral awards, commonly called the New York Convention, Cairn said in a letter addressed to the Indian High Commission in London.

“The government is not satisfied with the response/explanation given by these companies. Hence, the ban for these 59 apps is permanent now,” a section of business media quoted a source familiar with the notices as saying. It said the notices were issued last week.

The ministry’s June order stated that the apps were “prejudicial to sovereignty and integrity of India, defence of India, security of state and public order”.

Ageing signs include increasing cases of dam failures, progressively increasing costs of dam repair and maintenance, increasing reservoir sedimentation, and loss of a dam’s functionality and effectiveness, “strongly interconnected” manifestations, the report said.

“By 2050, most people on Earth will live downstream of tens of thousands of large dams built in the 20th century, many of them already operating at or beyond their design life,” according to the UN University analysis.
