Senior RTE executives are to be asked to explain the broadcaster's approach to legal threats, after reportedly paying €85,000 to settle a claim last month.
The Oireachtas communications committee's request comes amid debate about whether Ireland's libel laws will have a negative effect on coverage of next year's referendum on marriage for same-sex couples.
