Is adultery grounds for excommunication or other discipline in a Jehovah's Witness Church?

I think the title says it all. Are there rules/guidelines for Church Discipline for members of the Church that are blatantly involved in adultery? Specifically, I'm referring to well-known, unabashed involvement, not a one-time or short-term slip up. Understanding that we are all human and all able to fall into temptation, I am not referring to a situation where a person falls into sin, and then repents. I'm talking about openly unashamed sinful behavior. For example, a member becomes involved with a married man, becomes pregnant with his child, then works actively to break up the marriage, with no sign of a repentant spirit. Without focusing on what we think ought to happen, I'm looking for a defined policy or set of guidelines, similar to the Catholic guidelines , or those found in other denominations?
