How research worksResolution rules
This market will resolve to "Yes" if a writ calling for a parliamentary by-election in a UK parliamentary constituency is issued by the UK Clerk of the Crown in Chancery by the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No". The issuance of a writ must be confirmed within the specified timeframe to qualify. The primary resolution source for this market will be official information from the government of the United Kingdom, including the UK Parliament and the relevant local government conducting the election; however a consensus of credible reporting will also be used.
