 The blocker/s should be prepared to commit to trying to find a solution, but not necessarily form and present a solution by themselves. The TSC will look to facilitate a number of workshops to help understand the blocking objections, and form a new or amended proposal as a result. If the blocker/s are unable or unwilling to participate in attempts to find a solution, after multiple attempts, the original proposal is moved to a vote, as defined in this document, but additionally requiring a 75% super majority to pass. This will be at the discretion of the TSC Chairs.
