Before taking any action under this paragraph, the responsible authorities, acting jointly, must consult the Scientific Forum and such other experts as they consider appropriate.Words in Art. 5(2) substituted (31.12.2020) by The Invasive Non-native Species (Amendment etc.) (EU Exit) Regulations 2019 (S.I. 2019/223), regs. 1(1)(b), 5(5)(b)(i) (with reg. 2(1)(a)) (as amended by S.I. 2020/1590, regs. 1(1)(b)(i), 6(2)); 2020 c. 1, Sch. 5 para. 1(1)Words in Art. 5(2) substituted (31.12.2020) by The Invasive Non-native Species (Amendment etc.) (EU Exit) Regulations 2019 (S.I. 2019/223), regs. 1(1)(b), 5(5)(b)(ii) (with reg. 2(1)(a)) (as amended by S.I. 2020/1590, regs. 1(1)(b)(i), 6(2)); 2020 c. 1, Sch. 5 para. 1(1)Words in Art. 5(2) omitted (31.12.2020) by virtue of The Invasive Non-native Species (Amendment etc.) (EU Exit) Regulations 2019 (S.I. 2019/223), regs. 1(1)(b), 5(5)(b)(iii) (with reg. 2(1)(a)) (as amended by S.I. 2020/1590, regs. 1(1)(b)(i), 6(2)); 2020 c. 1, Sch. 5 para. 1(1); and (S.)
