Yes.
There are some jurisdictions that have adopted codes of conduct that apply to all forms of harassment, but they carve out parliamentary proceedings. For example, the Senate has a policy that applies to conduct between senators, but it does not apply to all actions that take place during parliamentary proceedings. Everything that takes place during parliamentary proceedings will be addressed through the procedural means that are already available, be it a question of privilege or a question of decorum, which are usually enforced by the chair or the Speaker.
