Can a Checks API plugin block submitting?

[Kate]

Is it possible for a Checks API plugin to block submitting a change, or is that only possible by voting?

I know I can add a related label to a check run, but that then only displays a badge with the number of errors next to that label (which is already nice of course), but that badge does not block submitting, like a -1 vote would.

Is it possible to write a submit requirement that does not allow submitting unless all checks plugins return a `CheckRun` that completed successfully and does not show errors?

Thanks,
Kate
