Cairn secured an interiminterdict against Greenpeace in 2011 after about 40 campaigners, some dressed as polar bears, barricaded themselves in Cairn's offices in Edinburgh.
Lisini applied to have the earlier interiminterdict recalled, which the SPL did not oppose and Lord Woolman granted the motion at the Court of Session in Edinburgh last year.
Since the hearing was for an interdict ad interim (temporary injunction), IW might have to show that it could afford to pay all Microsoft's costs and losses if Microsoft won at a full hearing but lost at the preliminary hearing.
