Generally that's not the way the law works. If corrections/refilings prior to the deadline aren’t allowed that has to be stated in the law. He refiled the corrected form before the deadline. He met the stated requirements of the law, as there are no previsions to the contrary. There is nothing supporting the States position that corrections prior to the deadline are not allowed. Zip.
Even if you are correct (which I will concede only for the sake of argument), the article clearly states that McClintock failed to place evidence before the judge showing that he had made a timely refiling.
I repeat: Ever since Florida, we've been the ones insisting that elections be run by the letter of the rules. When there weren't enough precinct workers in St. Louis and the Dems wanted the polling hours extended, we hollored fraud -- and were right to do so. So it sounds more than a little odd to hear a Republican crying about "technicalities". It is also extremely bizarre for a candidate who is running as an experienced professional screw up this way.
