I can only presume you are completely ignorant of the legal system in America.
They had every oppertunity allowed to them.

The courts aren't set up to make a judgment.
there was no authority of any court to make a decision.
"No specific authority instructs this court (let alone a reasonable public official) how to treat the ejection of a silent attendee from an official speech based on the attendee?s protected expression outside the speech area,? wrote Judge Paul Kelly of the Tenth US Circuit Court of Appeals.
You missed/left out something:
"A federal judge threw the lawsuit out. A federal appeals court panel agreed. The panel, in a 2-1 decision, said there was no ?clearly established? constitutional right not to be excluded from a speech by the president because of a bumper sticker on the car in which they arrived."
. the ruling by a judge that all or a portion (one or more of the causes of action) of the plaintiff's lawsuit is terminated (thrown out) at that point without further evidence or testimony. This judgment may be made before, during or at the end of a trial, when the judge becomes convinced that the plaintiff has not and cannot prove his/her/its case. This can be based on the complaint failing to allege a cause of action, on a motion for summary judgment, plaintiff's opening statement of what will be proved, or on some development in the evidence by either side which bars judgment for the plaintiff. The judge may dismiss on his own or upon motion by the defendant. The plaintiff may voluntarily dismiss a cause of action before or during trial if the case is settled, if it is not provable or trial strategy dictates getting rid of a weak claim. A defendant may be "dismissed" from a lawsuit, meaning the suit is dropped against that party.
That's why rags like the Washington Times have started mimicking The Onion with reports of someone that disagrees with Obama being ejected from his speech. I'll never understand that group of people that insist on mimicking ostriches.
