CARMEL, Ind. – Administrators at Carmel High School are feeling the heat after they allegedly trashed a sign put up by a pro-life student club, then forced club members into signing a secret agreement to limit future displays and discussions.

Students with Carmel High’s Carmel Teens for Life spent more than 25 hours painting a pro-life poster with 300 hearts – each representing 10 lives – along with the written statement “3,000 Lives Are Ended Each Day,” but administrators tossed the display after another student complained it was “offensive,” according to a district complaint cited by Fox 59.

The Liberty Counsel, a nonprofit religious freedom group, recently sent a letter to district officials complaining about how Carmel High administrators treated the pro-life students, which the organization claims violated the students’ constitutional rights.

Liberty Counsel contends the pro-life poster was approved for display and students followed club sign guidelines, but school officials decided to tear down the display because it promoted an “ideology” that’s “not approved for display,” according to the news site.

Officials allegedly removed the sign and threw it away, rather than ask students to remove it, because school signs cannot “interfere with what folks are thinking or feeling comfortable with,” the Liberty Counsel wrote.

The nonprofit pointed out that other controversial clubs, such as student organizations promoting LGBT rights, have not faced the same standard. Regardless, school officials not only trashed the Carmel Teens for Life poster, they pressured members into agreeing to terms about future communications.

The Indy Star reports:

Administrators reportedly had members of the club sign an agreement, which prohibits the club from using the word “abortion” in future displays or other forms of communication. Liberty Counsel says the agreement said students couldn’t contact legal assistance or take the agreement to their parents.

The organization says members were threatened that if they did not sign the agreement immediately, the club sponsors would be forced to resign.

Carmel Clay Schools officials released a statement Tuesday that confirmed they received the letter from the Liberty Counsel on Dec. 5 and forwarded the concerns to district attorneys for review.

“Less than 24 hours after receiving the letter, CCS counsel contacted Liberty Counsel in an effort to amicably resolve the situation and offered to provide preliminary response by December 16, 2016,” the statement read.

“Carmel Clay Schools’ staff and administration are treating the claims made in this letter very seriously,” it continued. “We are reviewing the matter to determine what happened and to respond to our students and community in an appropriate and respectful manner.”

Mat Staver, founder of Liberty Council, told Fox 59 the group will ensure administrators are held accountable for their “outrageous” behavior.

“By allowing other student clubs to post their viewpoints throughout the school while banning a poster from Carmel Teens for Life, the school has engaged in unconstitutional viewpoint discrimination,” he said. “Schools also may not censor pro-life viewpoints. The actions of the school officials are outrageous. Not only did they censor protected speech, they threatened students with retaliation if they sought legal counsel.

“We will hold this school and these officials accountable,” Staver promised.
