In March 2010, following the publication of the House of Commons Science and Technology Committee's report "Evidence Check 2: Homeopathy", Horam signed Early Day Motion 908: Science and Technology Committee Report on Homeopathy, which was critical of the report.
In May 2008 in the abortion amendments to the Human Fertilisation and Embryology Bill (now Act), John Horam voted for the abortion time limit to be lowered to 22 weeks against scientific and medical consensus which is currently 24 weeks. After four separate parliamentary votes on varying time limits, the majority of MPs voted to keep the abortion time limit at 24 weeks, in keeping with scientific and medical consensus, hence no abortion amendments were added to the bill.
John Horam was one of 79 MPs who signed Early Day Motion 377 noting the achievements of Charles Darwin, and calling for Darwin's birthday to be designated a public holiday to honour "one of the fathers of modern science and one of Britain's greatest, if not the greatest, scientific minds."
Libel Law Reform
In February 2010, John Horam signed Early Day Motion 423 calling for a reform of the English libel law. The motion noted that human rights activists, scientists, writers and journalists are currently prevented from publishing, and the public prevented from reading, matters of strong public interest due to the chilling effect of the law.
