Can a mere declaration of aspirants of their willingness to be substituted enough ground to declare them a nuisance bet?

For Commission on Elections (Comelec) spokesperson James Jimenez its not.
"A mere declaration to the contrary, in my opinion, wouldn't be sufficient to overcome the intention to run, which is manifested in the verified COC (certificate of candidacy)," he said in a statement on Wednesday, Oct. 13.
Jimenez added that the lack of a bona fide intention to run needs to be proven.
Some aspirants in the May 2022 polls have expressed willingness to be substituted.
Last week, retired Comelec Commissioner Luie Guia said if one files a COC to be a mere placeholder, "he/she clearly has no bona fide intention to run, which under Section 69 of the Omnibus Election Code, is what makes the filer a nuisance candidate."
"The most appropriate petition to file against someone suspected of filing a COC as a mere placeholder is a Petition to Declare a Candidate a Nuisance Candidate under Section 69 of the Election Code. If the petition succeeds, there is no candidate to substitute," he said on Twitter.
Section 69 of the OEC states that the Commission may, motu proprio or upon a verified petition of an interested party, refuse to give due course to or cancel a COC.
This is in cases where it is shown that it is filed to put the election process in mockery or disrepute, or to cause confusion among the voters by the similarity of the names of the registered candidates, or by other circumstances or acts which clearly demonstrate that the candidate has no bona fide intention to run for the office.
