Alterations in a printed bill

28.21After a bill has been printed and circulated, it is permissible to correct only a clerical or printing error. A corrected copy of the bill is usually made available electronically and in print in substitution for the first version.1 In minor cases, the Speaker has called attention to errors before second reading2 or at other stages, as appropriate.3 For minor alterations in the text of a bill made at later stages by silent correction rather than by amendment, see para 30.83.
