The widow of a Nigerian activist plans to take legal action against oil major Shell in Dutch courts.
Esther Kiobel has filed an application in New York after alleging the firm was complicit in the execution of her husband by the Nigerian military in 1995.
According to court documents filed in the US, the court papers have been filed so they can be used in the Dutch action.
The filings with the US District Court for the Southern District Court of New York show Kiobel plans to file the action before the end of the year.
A memorandum in the application filed last week said: “Ms Kiobel will demonstrate that Shell encouraged, facilitated, and conspired with the Nigerian government to commit human rights violations against the the Ogoni people.”
Shell has said it remains “fully committed” to supporting human rights in line with the legitimate role of business.
A spokesman added: “We have always denied, in the strongest possible terms, the allegations made by the plaintiffs in this tragic case.”
Kiobel had previously took her lawsuit to the US but the US Supreme Court in 2013 said the case could not be heard because of the alleged activities which took place outside the country.
Prior to the ruling Shell had agreed to pay $15.5million to settle lawsuits related to other activists executed at the same time as Barinem Kiobel, including the author and environmental activist Ken Saro-Wiwa.
The Nigerian military cracked down heavily on local opposition to oil production by a Shell joint venture in the Niger Delta in the early 1990s.
Kiobel alleges Shell provided support to the military in its crackdown.
