A Japanese court on Tuesday ordered a nuclear power plant in Hokkaido to remain offline as requested by over 1,000 plaintiffs due to safety concerns, in a rare decision issued while the operator is seeking permission from authorities to restart the plant.

The Sapporo District Court ruled that Hokkaido Electric Power Co. should not resume operation of all three reactors at its Tomari nuclear plant.

All three reactors had been taken offline for regular inspections by May 2012 and remain idled, with Hokkaido Electric Power undergoing screening by the Nuclear Regulation Authority to restart them under tighter rules introduced after the 2011 Fukushima crisis.

The plaintiffs argued there are active faults near the Tomari plant and in the nearby sea and the operator could be underestimating the size of potential earthquakes when designing the reactors' quake resistance.

They claimed soil liquefaction could occur around seawalls near the plant in the event of an earthquake and the utility has not taken sufficient measures to protect against tsunami.

The power company countered that there are no active faults around the nuclear complex or in the nearby sea, and that the possibility of soil liquefaction is low.
