Some court cases were tossed for filing errors or because the petitioners lacked standing. But most were tossed because they lacked merit based on the facts or the law. For instance, one in Pennsylvania wasn't heard because the claim was that observers we're not allowed to watch the count. It wasn't true. There were observers, the law was followed concerning who and how many. The lawsuit was tossed immediately because the claim wasn't true. Just because the trump lawyers thought their people should observe means nothing. That's their opinion, it's not law.
To claim the cases were never heard ignores the judicial process and is disingenuous at best.
