I don't believe tacit consent or approval can apply to traditional bishops.
I do not know if this was referring to my post, but if so, we are agreed. It cannot apply to the traditional bishops, but it can apply to diocesan bishops who are received into the the diocese by their diocesan clergy, as this recognition would give them legitimacy and the tacit recognition of the pope.
The pope now appoints all bishops. Why would the Diocesan clergy "receive" any other candidate? Their approval isn't necessary, nor do they have any role in choosing the candidate.
I am referring to a case where there is no pope. That was the context. I was responding to the article from Bp. Pivarunas, which gives the names of some diocesan bishops who were recognized as bishops during a state of sedevacante.
The principle is clear and Catholic. During a state of sedevacante, diocesan bishops can fill the vacancy of their diocese by tacit recognition of the pope, as they are received into their diocese by the clergy of that diocese.
This has not been done in this crisis, but it has been recognized as lawful in the history of the Church. Read more here:
