The case of the petitioners is that the respondents have seized the subject vehicles on 18.09.2020 and when the petitioners approached the second respondent seeking release of the same, they refused the same on the alleged ground of illegal excavation of gravel in Survey Nos.395/3, 4 and 5 of B.P. Varakattu village in Cheepurupalli Mandal, which belonged to D-Form pattadars i.e., respondents 4 to 6; petitioners brought to the notice of the second respondent that they have hired the vehicles to respondents 4 to 6 and that they did not have any knowledge of illegal excavation of gravel; the second respondent issued show cause notice to the respondents 4 to 6 on 26.09.2020 and they also submitted their explanation on 03.10.2020; not satisfied with the said explanation, demand notice was issued in October 2020 directing the respondents 4 to 6 to pay penalty of Rs.4,60,21,745/-; as the petitioners are not at all concerned with the illegal excavation of gravel, they seek release of the subject vehicles.
