If you are selected as the winner and can’t accept the prize, you will not be able to give the prize to someone else or designate someone else as the winner.

If you are not able, or don’t want to collect your prize, the jury may award the second place proposal with the prize. If you choose to collect a prize, you will be responsible for all taxes related to accepting the prize.

Even if the intention is to implement the winning proposal, the City of Stockholm cannot guarantee that this will be the case. If none of the proposals are deemed of high enough quality, the City of Stockholm may decide to not award a prize.

The competitor owns the rights to the proposal. After revealing the winning proposal, the City of Stockholm has the right to use the winning proposal.

The City of Stockholm shall receive a perpetual, worldwide, non-exclusive right and license to freely use (eg, store, load, process, reflect, read, show, test, understand, reproduce and otherwise dispose of and use) the entry and the rights related thereto (including associated intellectual property rights) in their operations.

The competitor owns the rights to his or her idea and winning the challenge is an opportunity – but not a guarantee – to get the idea implemented.

Note: the City of Stockholm may provide guidance for the winner in how to improve the proposal after the competition is over, based on the knowledge that has been gleaned during the evaluations of other submissions in the competition. It may be the case that the results in the competition create a base for future improvements. If the City of Stockholm wishes to use the proposal, either in full or in part, the City of Stockholm and the competitor should agree on terms about usage and ownership of the proposal.
