As a lawyer, is it a defense to allegations of false statements or pleadings that I, as a lawyer, personally believe the statements?

The Pennsylvania Supreme Court in opinions in the past like to cite the famous Daniel Webster quote of “Show me an honest man and I will show you an attorney.” Integrity and honesty are the hallmarks of the legal profession. When one is dealing with a lawyer either as opposing counsel or a client or as a judge, one should expect a lawyer will be honest and demonstrate integrity and not mislead. There is no room for white lies or cutting corners in terms of representations to the court, clients, or opposing counsel.
